Hello everyone!
I'm doing a line integral but I'm confused on the integration method used:
I got to integral 1 to 3 2*(x^4+xln(x) ); But they then have:
x^5/5 + 1/2x^2 * ln(x) - 1/4x^2 and I'm not sure how they got the last part, 1/2x^2 * ln(x) - 1/4x^2
Thanks!
u = x isn't what they did I don't think, and its been awhile so I'm rusty on integration XD
