Am I taking the antiderivative of |x| correctly? Edit: forgot +C, sorry So I remember seeing this video by Blackpenredpen on the Youtube homepage around 3 months ago where he was showing failed attempts of him trying to figure out how to get$$\int\sqrt{\sin^2(x)} \,dx=\int\left|\sin(x)\right| \, dx=-\cot(x)\left|\sin(x)\right|+c$$without pie...

So what I want to know is: Is there a way to solve every non-algebraically solvable equation of that form? Here is ... (more) |
