You could just pull out the half: it will be (1/2) cos squared x.
No, it is not. To be correct, the expression requires parenthesis, which are missing.
No, they do not.
No, it does not.
None of the graphs that I can see!
The law of cosines with a right angle is just the pythagorean theorem. The cosine of 90 degrees is 0. That is why the hypotenuse squared is equal to the sum of both of the legs squared
Cosine squared theta = 1 + Sine squared theta
No, it is not. To be correct, the expression requires parenthesis, which are missing.

2 x cosine squared x -1 which also equals cos (2x)

E = MC squared means that Energy is equal to Mass times a Constant (which is the speed of light) squared.
x = -10 or x = 10
(watts equal) voltage times current (e x I ) 120 x 20 resistance times current squared (r x I squared) 6 ohms x20 squared voltage squared divided by resistance (E squared divided by resistance) 120squared divided by 6 check OHMS LAW,
F is force and it is equal to the gravitational constant times the mass of the first object times the mass of the second object divided by the distance between the two squared.
