Ok, so i have a problem from my book that I can't figure out how to start,
so the integral is from 0 to 4 (not important) and it is (x/(1+2x)^1/2 ) dx
thats x over radical 1+2x
i can't see any value in the equation for "u" that will remove x from the equation. Could someone please explain what you would select for "u" and why? Do you have to modify the integrand before proceeding?
