How would you graph sin 4x = 1 ? a) How do you find amplitude? b) How do you find Period? I'm kind of confused about the "=1" part. Thanks :)

Differentiate 1/tanx I got -sec^2 / tan^2x, which is correct, but the answers said I could also simplify this to -cosec^2. How would you do that? Thanks =)

Differentiate (1- sinx) / (1 +sinx) How would I do this? The answer is (-2cosx)/ (1 + sinx)^2 Thanks in advance :)!!

Differentiate (sin^3)x and use this result to evaluate the integral of sin^2 x cos x dx between pi/2 and 0. Thanks!
