Answer 2

Sin (45+theta) - Cos (45 - theta) is Sin 45 is 1/√2 Cos 45 is1/√2 1/√2-1/√2 =0.

For disentanglement lets take x pivot to be in extend [0– 90] degrees.

Presently in light of the fact that Sin work isn't standard it's not 1/2 for 45 degrees else it would have been a straight line with 45 degree slant or triangular wave or possibly some other unpredictable bend.
