Thanks for the response however using that substitution I end up with , which I don't know how to integrate. Thanks

hehe i knew I was doing somethign right... thanks a lot, our maths lecturer at uni is German and she uses Log when she means ln in the notes i just copied it straight out
Hello, slevvio! I have to integrate the following by substitution. .? . . . This cannot be integrated by substitution alone. We must integrate by parts . . . . . Then we have: . . . . . . . . etc.
