Where Can I Find Engineering Exam Questions Online?

Click For Summary

Discussion Overview

The discussion revolves around finding online resources for engineering exam questions, with participants sharing links and methods for locating such materials. Additionally, there is a side inquiry into solving a specific mathematical equation involving summation and series.

Discussion Character

  • Exploratory, Technical explanation, Homework-related, Mathematical reasoning

Main Points Raised

  • One participant requests information on where to find engineering exam questions from various universities.
  • Another participant suggests the MIT OpenCourseWare website as a resource for tests across different courses.
  • It is noted that a simple Google search can yield numerous sample questions, both solved and unsolved.
  • A participant introduces a mathematical problem involving the summation of an exponential function, questioning the analytic methods available for solving it when the number of additions is large.
  • Another participant advises finding a closed expression for the sum of the series and equating it to a known sum to solve for the variable.
  • A later reply indicates that using a computer to assist with the calculations has improved efficiency.

Areas of Agreement / Disagreement

Participants generally agree on the availability of online resources for engineering exam questions, but the mathematical problem remains unresolved with no consensus on the best approach to solve it.

Contextual Notes

The discussion includes a specific mathematical inquiry that may depend on the definitions of summation and series, and the assumptions regarding the variables involved are not fully articulated.

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.
 
Mathematics news on Phys.org
Just on Googling you can find a lots of sample questions solved and unsolved.
 
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
