Question

prove that it is is is is is .................

Answer 1

Given Equation is (cosec theta - cot theta)^2

                            = (1/sin theta - cos theta/sin theta)^2

                            = (1 - cos theta)^2/sin^2 theta

                            = (1 - cos theta)^2/1 - cos^2 theta

We know that (a - b)^2 = (a - b)(a + b)

                            = 1 - cos theta * 1 - cos theta/1 - cos theta * 1 + cos theta

                            = 1 - cos theta/1 + cos theta.

LHS = RHS


Hope this helps!
