do you mean (-)Cosine(X), or arcCosine(X)

The first is graphed as "-cos(X" (no quotes)

The second as "cos-1(x" (press 2nd Cos to access arcCosine)

First, make sure you have the appropriate angular mode set. To change the angular mode, press MODE, use the arrow keys to highlight either "RADIAN" or "DEGREE" on the third line, press ENTER, then press 2ND [QUIT].

Press the appropriate sin, cos, or tan key (two rows above the 7, 8, and 9 keys), enter the angle, close the parenthesis, and press ENTER. For example, to calculate the sin of 2.1, press

SIN 2 . 1 ) ENTER

Take the cosine of the number (cos key), square the result (x2 key).
Make sure the calculator is in DEG and not RAD mode. Most elementary trig is conducted in degrees, not radians.

You're both right, in a way. (-64)^3 is -262144. The square root of that is +/- 512i. Take your choice as to the sign.

For what it's worth, the TI-84, TI-86, TI-89, and the HP 50g all go with the negative value.

Here's how in 4 easy steps (I substituted "A" for "X", my more favorite variable.):

1.) Set calculator to "Degree"

2.) Given-- (cos( X))

3.) Given--(4.37/7.25)==> (437/725)

4.) Add--(cos( X)+ (437/725)

(cos(x))^2

when you type -2 imagine your calculator doing the equation: -1 x 2. The - sign actually stands for a -1 so when you do -2 squared your calculator is simply following order of operations. It first squares the 2 making it 4, then it multiplies the negative making it -4. In order to get around this you must use parenthese. (-2)^2.
