Question 969566: NOTE: THIS IS A CALCULUS 2 INTEGRATION PROBLEM USING U- SUBSTITUTION METHOD. Any help is greatly appreciated!
The question is asking integral of (sinx)/(cosx).
I know how to do this if I choose u=cosx and du=-sinx, or and I know I can aslo chnage the orignal problem to tan x,
But I wanted to do it using u=sinx and du=cosx so that we have the integral of u/du
but for some reason when I do this I get the wrong answer. ((cosx)^2)/2 is not the correct answer.
