Approximate the improper integral $$\int^{\frac {\pi}4}_0 \frac {\cos x~dx}{\sqrt{x}}$$ in these ways:
(a) using Riemann Sums
(b) First make the substitution $u$ $=$ ${\sqrt{x}}$ and then use Riemann sums
Hi! I was just reading a little about Riemann Sums and learning what improper integrals are. Is it possible that we can approximate this. I spoke to some people and they said know but one said yes.
Is it ok if you explain the working for me. I know I am teaching this to myself but your explaining would help. I would like to get head start on this topic. Please can you help me. Thanks!
