## Engineering Mathematics

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.

 PhysOrg.com science news on PhysOrg.com >> 'Whodunnit' of Irish potato famine solved>> The mammoth's lament: Study shows how cosmic impact sparked devastating climate change>> Curiosity Mars rover drills second rock target
 http://ocw.mit.edu/courses/ has many tests in different courses :)
 Just on Googling you can find a lots of sample questions solved and unsolved.

## Engineering Mathematics

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
