I'm getting a different answer than the solutions sheet for problem set 1, section F, question 7b.

The solutions sheet and I both used the quotient rule, (u'v-uv')/v^2, but the sheet multiplies the result by (v^2)', and I don't know why.

Nevermind, I was doing the derivative of a sqrt(1-v^2/c^2) wrong.
