there is thing called "Quick formula I" that is used for integration. can some1 exlain to me how to use it ? like in words and stuff so that i can actually understand
The only mnemonic I recall using as a student was for integration by parts. To decide which part of the integrand/differential to try as u, we were taught to use whichever of the following is part of the integral, in the order of precedence by the LIATE rule.
