algebra 2 logs and trig
It's csc 2x, and I got it down to this before but I don't know if I can use your hint from there or if I should start from square one: log(base 2)csc(x) = log(base 4)csc(4x^2) Would that become the following? log(base 2)csc(x) = 2log(base2)csc(4x^2)

Well the original problem was the following but I worked it out to what I put here before: log(base 2)cotx - 2log(base 4)csc2x = log(base 2)cosx I switched the cosx and the csc2x and used properties of logs to get log(base 2)cscx, but maybe I'm wrong in doing that. is ...
