cot⁡ sin⁡ cos⁡ = 1- sin⁡ 2

Please note that this site does not let you to cut and paste math symbols from other applications - all we see is gibberish. Please resubmit and this time please type out the equation manually.

However, I'm guessing, but if what you meant to type is this:


cot(a) \times \sin(a) \times \cos(a) = 1 -\sin^2(a)


then it's simply a matter of replacing cot(a) by cos(a)/sin(a), and employing the basic identity \cos^2(a) + \sin^2(a) = 1.
