Thank You for this! I've been watching numerous videos to figure out how to do this, and none have thoroughly explained it as much as this one!

Nothing like doing math at 2 in the morning, about to pull of the greatest academic come back of the year in math with a test and a packet of homework that's due in about 8 hours. 😌👍 What a life saver.

But the question is, why do you choose to multiply by (1-sinx)? in the beginning?

I have a simple idea write sin(π/2-x) in place of cosx and cos(π/2-x) for sinx .And we got it in the required form .use 1-cosx formula I.e 2sin^2x/2... And so on they have given like this to confuse us that's all😂

You can cross multiply, then Pythagorean then, 1=1

multiply RHS by zero and LHS by zero
Zero = zero hence proved😅😅😅
