Question

Find the charge q(t) flowing through an device if the current is:

(c) i(t)= 20 cos(10t + π/6)10^-6A, q(0)=2(10^-6)C

My problem in this question is the substitution.

I know that u=10t+π\6 , and u'=10, but the u' doesn't equal to the 20 in front of the cos, how do I find the derivative that will equal the "20".
