1. The problem statement, all variables and given/known data Find the general indefinite integral of sinx/1-(sinx)^2 3. The attempt at a solution I arrived at tanxsecx(dx), rewrote it as sinx(1/cos^2 x) = cosxtanx = sinx However, I know that the correct answer is secx. WHY? Can anyone explain why using trig functions (ie, without using u as a substitution)?
