Calculating charge from an equation for current

Calculating charge from an equation for current.

As electrical technology students, you all, of course, remember that current, i is the derivative of charge, q with respect to time:

     i = dq/dt

So:

   
*

Now:

Current in a certain wire changes as i = (1 + 3t)1/3. How many coulombs of charge pass a specified point in 3 seconds?

Now do the substitution. What do you assign for u, n and du?
