Is anyone here a pro or familiar with using 'U substitution' in calculus? I have a few problems that I'm having some problems with so if anyone would be willing to take a quick look and point me in the right direction, that'd be awesome. Thank in advance.
ETA: I had like 30 of these problems and I can't seem to get these four.
Solve the following using u-substitution 1. ∫ x * √(2-x) dx 2. ∫ 1 / (x * ln√x) dx 3. ∫ (e^√x) / √x dx 4. ∫ (x^2 + 2) / √(x-5) dx
