TRIGONOMETRY: "The  mathematician  is  fascinated  with  the  marvelous  beauty  of the forms  he  constructs,  and  in their  beauty  he  finds  everlasting  truth."

Example:

If xcosθ - ysinθ = a, xsinθ + ycos θ = b, prove that x2+y2=a2+b2.

Ans:    xcosθ - y sinθ = a xsinθ + y cosθ = b Squaring and adding x2+y2=a2+b2.
