Question

If x+2k is a factor of f(x)=x4-4k2x2+2x+3k+3, find k.

Answer 1

Answer:

To integrate cot^2x, also written as ∫cot2x dx, cot squared x, (cot x)^2, and cot^2(x)we start by using standard trig identities to simplify the integral to a form we can work with. We start with this standard and well-known trig identity for cot2x.
