## Sample Integrals with a Sage

Perhaps you would like to evaluate this antiderivative:
$$ \int 3\sin^2(2t) \, dt $$
You need to tell Sage that $t$ is a variable. You also need to use a $*$
to show multiplication. Be careful to match parentheses.

The *show* lets you see the result as typeset math.

Here is a definite integral
$$ \int_0^{2\pi} 3\sin^2(2t) \, dt $$
Note that the bounds of the integral are in a pair of parentheses with $t$.
