Question

Need help with this derivative

Answer 1

\[ \int\limits_{0}^{a}5x^2\sqrt{a^2-x^2}dx\]

Answer 2

isn't that integral?

Answer 3

sorry thats what I meant!

Answer 4

Are you familiar with trigonometric substitution? That calls for a substitution of the form
\[ x = a\sin(t)\]
\[dx = a\cos(t) \]

Answer 5

oops...
\[dx = a\cos(t) dt\]
