[SOLVED] Integrating substitution problem?
Sorry to hijack this thread sort of (as a similar named one already exists), but the title is aptly suited to my question.
I have integral to integrete and I don't really know how to do it tbh. . .
[tex] s=\int{\sqrt{2+(3t)^2}dt [/tex] Limits are from t=0 to t=5 (how do I show this on latek?)
If it was 2-3t then I'd simply substitute the t for sin u, but what do I do when it positive?
