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

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

To determine what negative sine squared plus cosine squared is equal to, start with the primary trigonometric identity, which is based on the pythagorean theorem...sin2(theta) + cos2(theta) = 1... and then solve for the question...cos2(theta) = 1 - sin2(theta)2 cos2(theta) = 1 - sin2(theta) + cos2(theta)2 cos2(theta) - 1 = - sin2(theta) + cos2(theta)

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
