# Finding the integral of x^a using a geometric progression

1. Jan 24, 2005

Let's say $$y = x^a$$ and you want to find $$\int^b_a x^a$$

How would you find this using a geometric progression?

Thanks

1.U forgot "dx" in the integral...
2.I'm sure u cannot use geometric progression,if $a=-1$
3.Do u know how to work with Riemann sums???
