## Homework Statement

There is a circuit diagram which I can't post atm and don't think it's relevant to my question.

Also: R

_{1}

=R

_{2}=10k and C=.1μF

And: Find V(t)

## Homework Equations

We're given the equation V(t)=1/RC ∫

^{t}

_{-∞}V

_{i}(t)e

^{-(t-τ)/RC}dτ

My problem is I don't recall what tau is here "τ" and I'm not sure what I should be using for the V

_{i}(τ).

I've been trying to find it in my notes and physics textbooks but I can't seem to find it. LOL I must be stuck on stupid because I know I've seen these and am familiar with them. If anyone has this book and has solved this problem please help me out. :D

## The Attempt at a Solution

Found V(t) by Thevenin Analysis to be .5V

_{i}also used Thevanin to find R

_{eq}=20K to replace the 1/R in the integral. Not sure what else to do.
