Alright. I understand. Thanks everyone!

I drew the graph, and I see how you can extend the line to figure out the y-intercept, thus an initial value. Thank you for that. So, re reading everything, I have figured out many different way to solve this. Would the differential equation approach to this (from post #2) be the only way to...

Thanks Nascent. I see how I can solve it in that manner, which is much easier. However, I think my ELC professor wants to see the work via calculus.

Thank you so much. This makes sense. It's been a while since I've practiced calculus. There is one more thing I don't understand. How and why would I pick to evaluate q(2) to find the c in q2 = 2t + c. If the bounds on the piece wise function remain the same, it appears that q(2) doesn't exist...

Homework Statement P 1.2-4 Homework Equations I know that i(t) [current w/respect to time] = dq/dt. I also know that by the previous equation, q(t) = ∫i(τ) from -∞ to t (sec). The Attempt at a Solution I understand simpler problems involving finding q(t) by using the integral relationship...
