Want to Change the Future, Study Your Math and Go With Zero Robotics
Almost everyone loved that show "Robot Wars" and it was very cool indeed. Yes, that probably will be the wave of the future when it comes to security and military. Still, someone has to make all those robots and design that future; build them, program them, operate them, and plan for that potential eventuality. Those who do will be gainfully employed, and have a very rewarding career with a unique and highly sought-after skill.
However, don't expect to be amongst the elite in the robotics industry if you don't study your math today because those jobs will not be available to you in the future, unless you do. Robotic technicians, programmers, and those involved in developing all the applications will need robust knowledge of mathematics to do their jobs. Yes, it is yet another reason to hit the books and study math in high school and college and work your way up the ladder taking the college prep classes and advanced mathematics courses.
There was a great article recently on the Zero Robotic Website. Oh so you are wondering what Zero Robotics is? It's a high-school competition, put on by MIT, DARPA, and NASA which creates miniature floating robots at the ISS (International Space Station) which can fly in formation and do tasks. These miniature robots are called SPHERES for; Synchronized Position Hold Engage and Reorient Experimental Satellites. I mean this is WAY COOL STUFF!
Okay so, the MIT/High School Teams "had a "Pilot" event in 2009 with ten High School students (grades 9-12), a Nationwide Pilot in 2010 with over 200 High School students from 19 US states and a summer program (NASA Summer of Innovation) in 2010 with over 150 middle school students (grades 5-8)."
This is awesome no doubt but guess what? If you don't study your math it is very doubtful that you'll be able to participate. Those who study their math can enter the robotics programming competition, and their robots may be taken into space. Imagine participating in programs like these, and such programs are on-going throughout our nation, not just for space, but in all sorts of industries.
You can participate and find yourself in a lucrative niche in the future, that is if you hit those books today, study your math, and move your knowledge, talent, and know-how up that ladder. It all starts with a little math, and you are going to need to know it, that is if you want a piece of the robotic age and future. Please consider all this and think on it.

Geometry for Beginners - How to Find the Area of a Circle
Welcome to Geometry for Beginners. This article returns to the concept of finding area, but this time the figure will be a circle rather than a polygon. Terms we have used previously for finding area - like base and height - do not apply to circles, so new terminology becomes necessary. In addition, we need to understand some concepts we have never encountered before to understand the derivation of the formula.
Note: Some mathematicians do, in fact, consider a circle to be a polygon - a polygon with an infinite number of sides. The concept of "infinite number of sides" comes from Calculus, but a few mental images can help Geometry students understand the basic idea. Get a piece of paper if your ability to visualize images in your mind is as weak as mine. Now, draw (either on paper or on your mental whiteboard) a triangle. With the triangle and all the other figures, try to make all the sides equal in length. Now, move to the right of the triangle and draw a square of similar size. Move right again, and draw a pentagon. Then draw a hexagon and an octagon. This is generally enough figures to see the pattern that as the number of sides increases, the polygon becomes more and more circular.
In Calculus, we consider what the "end result" would be if we could continue to increase the number of sides of a polygon forever. We call this end result the "limit." For our situation, a polygon with an infinite number of sides would have a circle as its limit.
In addition to understanding this limit concept, we also need to review the meaning of pi before we can understand the formula for area of a circle. Remember that the irrational number pi is the ratio of the circumference of a circle (distance around) to its diameter (distance across through the center). Also, remember that circumference is equivalent to the perimeter of polygons and has two possible formulas: C = (pi)d or C = 2(pi)r. Now we are ready to find the area of circles.
We already know that area is measured with squares; and, for rectangles, those squares are easy to see and count. Unfortunately, squares don't fit into circles nicely. To understand the area formula for circles, we need good mental image skills and a good understanding of the "limit" concept mentioned earlier in this article.
On your "paper" draw a circle with a diameter of 1 to 2 inches. Now, divide this circle into 4 equal parts by drawing another diameter perpendicular to the original diameter. You should now be able to see 4 shapes like pieces of pizza. Now, take those 4 pieces and fit them side by side but alternating point up and then point down. We now have a parallelogram-type figure having two bumps or curves on both the top and bottom and a rather steep lean to the side.
Now we are going to do the same type of limit process we discussed earlier. Look back at your circle with 4 parts. Draw two more diameters to divide each part in half. You should now see eight pie-shaped pieces that are the same "height" as before, but are more narrow. Take these eight pieces and fit them side by side, again alternating point up and point down. Again, we have that parallelogram-type shape, but now the lean to the side is decreased. Said in a different way, the sides are becoming more vertical. In addition, the top and bottom now have four bumps or curves each, but the curves are flatter.
As we continue to divide the circle into more and more pie pieces and continue fitting the pieces together side by side as before, the resulting figure becomes a rectangle because the sides become vertical and the curves on the top and bottom flatten completely. The height of this resulting rectangle is really the radius of the circle, r. The top and bottom of the rectangle come from the circumference. This means the base is one-half of the circumference, C.
The area of the circle is the same as the area of the rectangle. The rectangle area formula can, thus, change from A = bh to A = (1/2C)(r). Remembering the formula for circumference, we can change the area formula even further. A = (1/2C)(r) becomes A = 1/2(2(pi)r)(r). By simplifying the multiplication, the result is A = (pi)r^2.
This circle area formula, A = (pi)r^2, can be used to find the area if we know either the radius or diameter of the circle; or we can find what the radius or diameter must be for a given area.
For example: If the radius of a circle is 5 cm., find the area of the circle.
Solution: A = (pi)r^2 becomes A = (pi)5^2 or A = 25pi. The final form of the answer will depend on the teacher, the situation, or the subject. Sometimes, we want the answer in terms of pi because this is the EXACT answer, but we mentally estimate for meaning using 3 as the value of pi. Thus, the circle has an exact area of 25pi sq. cm. which is about 75 sq. cm. Other situations require a more accurate decimal value for the area, so we use the pi key on the calculator.
3 Final Cautions About Circles:
1. Answers with pi are EXACT, while decimals are APPROXIMATIONS.
2. Radius and diameter are often confused. Using the wrong value is very easy. THINK!
3. The circumference and area formulas are similar and easy to confuse. THINK before you start working on with a formula!

The GED Math Test: About the Casio fx-260 Calculator
To score well on the GED math test, it's important to learn how to use the Casio fx-260 calculator, since it's the calculator used for the official General Education Development Test. To prepare well for the test, it's a good idea to get hands-on practice with this Casio, and to understand which calculator functions the test expects you to know.
The Casio fx-260 is used for Part 1 of the two-part math test, which covers basic algebra and geometry, data analysis and basic number operations. Each one of the two parts has 25 questions, with 45 minutes slotted, or 90 minutes total allowed for the entire GED math test. The Casio fx-260 is distributed by the test site center for Part 1 of the test, and then collected before part 2. Calculators can't be used for Part 2.
About the Casio Calculator
The Casio fx-260 is a scientific calculator. It's more advanced than the simpler or basic calculator models most adults use to balance their checkbooks or to add a grocery bill while shopping. Many of today's high schoolers and even college graduates aren't familiar with the advanced calculators and multiple functions of scientific calculators used in today's technology, science fields and for advanced financial operations. So calculator skills aren't just important for GED students; knowledge of scientific calculators is important to everyone engaged in today's rapidly progressive technological society.
Here are some basics to understand about the Casio fx-260:
Learn the location of the keys.
Learn the functions that the keys perform.
Use the 'On' button to reset the calculator, or to clear the memory.
How to use the 'Clear' and 'All Clear' buttons or functions to clear the last number entered or memory.
Using number keys 0-9, and basic operation keys for addition, multiplication, subtraction and division.
Learning the location of the decimal point key, equals and percent, and how and when each is used.
Using the 'Shift' key -- to change other keys to alternate functions.
How the 'Change Sign' and 'Fraction' keys work, and when to use them.
How the 'Square' and 'Square Root' keys work, and when to use them.
The 'Parenthesis' keys are important, since these keys are used to control the order of mathematical operations.
Understanding the keys to raise numbers to another power, and for exponentials -- 'EXP' key -- used in scientific notation.
Does it look complicated? Sure, and the Casio calculator used for the GED test has additional functions that can be used for highly complex mathematical functions.
But don't worry. While it seems like a lot to learn -- and to understand -- the test requires only basic knowledge and application of a few functions. And this knowledge will actually help test candidates solve the test's more complicated problems.
The Casio fx-260 is worth learning. Understanding goes a long way toward reducing "math anxiety" and should improve the final GED Test math score.
