Calculators

Yes, you can use a calculator. In fact, it is recommended. You can also use calculator programs while taking the math section of the SAT reasoning test. Visit www.calc-tech.com - there you can download the SAT Operating System, which is a software package for your graphing calculator that helps you complete problems faster and with greater accuracy during the actual test (the math section). You can also use the software to solve problems in your high school math class. You can raise your score by as much as 60 points (and often more) just by using the software.

The easiest way to use a fraction on the TI-84 is to type it in like this:

(1/2) for one half

Use the float feature found on the mode button. Press mode and then select a number next to FLOAT. If FLOAT is selected, the calculator will not round. Selecting a number next to float will round to that many decimal places.

X^2/a^2 + Y^2/b^2 = 1

a = 2

b = 4

X^2/4 + Y^2/16 = 1

multiply through by 4

X^2 + Y^2/4 = 4

Y^2/4 = 4 - X^2

Y^2 = 4(4 - X^2)

Y^2 = 16 - 4X^2

Y = +/- sqrt(16 - 4X^2)

one of many ellipses possible ( don't for get to enter bot + and - terms )
