I see what you mean, my mistake, thank you for pointing it out. I see holes in my knowledge about understanding of basic integration now, will have to fill them in :)
That's what my prof does. By setting it from 0 to t, we ensure evaluated integral is equal to the true value with t as a variable, how would setting it to something arbitary as t_o (I'm assuming that's what you mean)be any better? My understanding of it is that we need to choose some...
Homework Statement
Suppose an RC series circuit has a variable resistor. If the resistance at time t is given by by R = a + bt, where a and b are known positive constants then the charge q(t) on the capacitor satisfies
(a+bt) q' + (1/C)q = V
where V is some constant. Also q(0) = q_0
Find q(t)...
