Homework Help: Calculus III

Posted by Sean on Sunday, March 16, 2008 at 7:47am.

I'm supposed to find the expression 'y', when

(x^2+100)y'=23

When y(10sqrt(3))=0

Also, I have to find the indefite integral
of

xsqrt(19x-7), using integration tables in teh back of the book "Calculus of a Single Variable, 8th Edition." Tables are in appendix B

I used the formula

[2/[b(2n-3)]]*([u^n]*(a+bu)^[3/2]-na[integral of [u^(n-1)sqrt[a+bu]]]

I've used
a=-7
b=19
u=x
du=xd
But it doesn't seem to work.
