Cosine squared theta = 1 + Sine squared theta
No, it is not. To be correct, the expression requires parenthesis, which are missing.
No, they do not.
No, it does not.
2 x cosine squared x -1 which also equals cos (2x)
None of the graphs that I can see!
E = MC squared means that Energy is equal to Mass times a Constant (which is the speed of light) squared.
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
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)
No, pressure is equal to force (Newtons) divided by area (metres squared)
