# Math Help - Totally Stuck -Integration

1. ## Totally Stuck -Integration

Sorry im new, hate doing this as i like to do things by myself...but I have been at this 2 days and cannot get anywhere.

Integration is not my strong point....

The charge (q), in couloms, on a capacitor can be obtained by integrating the current(i), in amperes,with respect to time. Determine the charge on a capacitor as a result of current flowing for three hundreths of a second if

(a) the current (i) is a constant 5mA

(b) the current, in mA, is a function of time given by

i=60t2 (squared)

Thanks to anyone who is kind enough to help me out.....

2. You do not seem to be struggling with integration. It seems the difficulty may be in simply understanding what the problem wants.

$\int_{0}^{0.03}\;5\;dt$

Can you tackle that?

$\int_{0}^{0.03}\;60\cdot t^{2}\;dt$
