trouble with a simple derivative
can someone please assist me real quick in taking the derivative of:

((2t+1)^(3/2))/3

I would write it as
$
\frac{1}{3} \left(2t + 1\right) ^{\frac{3}{2} }
$

then I think the derivative is...

$
\frac{1}{3} * \frac{3}{2}\left(2t + 1\right) ^{\frac{1}{2} } *2
$

So you take the derivative from the outer function ()^3/2 and then the derivative from the inner function 2t+1
