i have to integrate using u substitution, but i am not sure if i did it correct. tan^3(5x)sec^2(5x)dx u=5x du=5dx 1/5du=dx 1/5tan^3(u)sec^2(u)du 1/5tanusec^2u+c 1/5tan(5x)sec^2(5x)+c

Hi! Thank you very much for your help--- I'm not sure what the answer to this is; how do I solve? Find antiderivative of (1/(x^2))[sec(1/x)][tan(1/x)]dx I did integration by parts and got to (1/(x^2))[sec(1/x)] + 2*[antiderivative of (1/(x^3))(sec(1/x))dx]

how would you create an equation for sec(2x) using both sec(x) and csc(x)? the steps i have so far are 1/(cos^2(x)-sin^2(x)) = 1/(1-1)/(sec^2(x)-csc^2(x)) but then i do not know what to do after this.
