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
 
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...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Thread 'Imaginary Pythagorus'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
