Well, i was assigned to do this problem but i haven't yet covered the ln formula and my professor still wants me to do it.
Can someone please show me how to solve this particular integration (See Attachment)?
I want to start with integral on the left
first multiply the denominator and numerator with sec(y)+tan(y)
now you have the numerator is the derive of the denominator so the integral is ln(denominator) since the integrate of f'(x)/f(x) is ln(f(x)
this is the first
let dv=sec^2y and u=secy
and the integral in the right we integrate it before
