Compute an antiderivative for each of the following functions:

$\displaystyle a) f(x) = \frac{2x^3+1}{x^2}$

$\displaystyle b) g(x) = \sqrt{x}+x^\frac{7}{3}$

$\displaystyle c) h(x) = csc(2x)cot(2x)$

I was never taught integrals properly, only the basics where u change $\displaystyle x^2$ to $\displaystyle x^3/3$.

can anyone help? thanks!
