I just solved for each log individually on my calculator and used decimals to find the answer, and it ended up being right thanks!

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 d...

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)

I wanna find some one to taking my class. I will pay it.

I think so too. The independent variable is the number of papers and dependent is how long it takes them to deliver.
