Where Can I Find Engineering Exam Questions Online?

AI Thread Summary
Engineering exam questions can be found online through resources like MIT's OpenCourseWare, which offers a variety of tests across different subjects. A general search on Google also yields numerous sample questions, both solved and unsolved. The discussion includes a query about solving a specific equation involving a sum series, particularly when the number of additions becomes large. A suggestion is made to find a closed expression for the sum of e^k from 0 or 1 to n and then equate it to the known sum to solve for n. Overall, the conversation emphasizes the availability of resources for engineering exam questions and methods for tackling complex equations.

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
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
