Does anyone know where I can find engineering exam questions on the web. I am trying to do a survey of various questions from different universities.

I am trying to solve an equation that involves sum series and the unknown is the number of times i have to add, this is easy to solve just by guessing when the number of additions is small, but if it gets large.... is there any analytic way to solve this kind of equations?

form:

sum (e^n) from n b to x = a;

@diegojolin: find a closed expression for the sum(e^k), from 0 (or 1) to n.
then equate it to the known sum then solve for n.

Oks, thanks, I've tried and at least the computer seems to work faster this way
