NettetAll of the standard forms for integrals involve the following: (some function of u) (derivative of u -- note, of u, not the whole function) You must have the derivative of whatever you are calling u in order to use the form. If you don't have that derivative, then you have to solve the integral some other way. NettetI don't think you'll be able to solve this using 𝘶-substitution. I used integration by parts (it took two iterations). There are several integration by parts videos on KA. I'd …
