I used Wolfram Alpha to see that \(\int x^{1} dx=\ln\leftx\right+C\), even though I don't understand why. But what about \(\int f(x)^{1}dx\)? Wolfram Alpha couldn't come up with a formula. So, is this a problem when trying to solve with substitution?

That's basically the integral of 1/f(x) . There are many possibilities depending on what f(x) is.

you may have to use techniques other than substitution possibly.

For instance if f(x) is 1+x^2 than we have the integral of 1/(1+x^2) which is arctan(x) + c

Okay! So, if the function is know, then we just try to integrate it. Thank you!

I'm going to ask about the specific problem in another post. This one is done, thanks! :)
