Hi, the title pretty much speaks for itself. There are so many methods to use in 4u integration so how do you identify when to use usubstitution and what the value of u is? I came across the following question (part c) in which it already hints at using usubstitution and gives you the suitable value of u. However I wonder if the question did l not, how would you manage to solve it? Especially in this case, the given value of u is 1/x which is a bit unexpected to me.
Thank you so much for taking the time reading this!
