Wow, I feel dumb. Thanks for pointing that out, though.

1. The problem Find the definite integral. \int \frac {t^2 - 3}{-t^3 + 9t + 1} dt2. The attempt at a solution The answer is the book made it seem like the rule \int \frac {du}{u} = ln|u| + C was used. Here's what I got: u = -t^3 + 9t + 1 du = -3t^2 + 9\;dt -\frac{1}{3}du = t^2 + 9\;dt...

Homework Statement Two point charges lie along the y-axis. A charge of q_1 = -9.0 \times 10^{-6}\;C is at y = 6.0m, and a charge of q_2 = -8.0 \times 10^{-6}\;C is at y = -4.0m. Locate the point (other than infinity) at which the total electric field is zero.Homework Equations E =...
