1. The problem statement, all variables and given/known data Find the equation of the tangent at the point indicated y=3cscx x=pi/4 2. The attempt at a solution So to do the question you need a point (which im given), the slope and then you need to substitute that all into y=mx+b. I believe I have differentiated correctly with y=3(-cot(x)csc(x)) Then I find the slope by inserting pi/4 into the differentiated equation y=3(-cot(pi/4)csc(pi/4)) After this is done I put everything into y=mx+b, and this is where my problem is. Is there anyways to simplify 3csc(pi/4) and 3(-cot(pi/4)csc(pi/4))? I think I remember doing something similar in math a long time ago but I forgot now. The final answer does not include -cot or csc so there must be a way I dont remember.
