I had an interesting challenge earlier this year in physics class, and I got a good grade on my answer, but I'd like to see what other people think about this.
Energy is defined in the dictionary as being the ability to do work, while work is defined as the application of energy (roughly...
Huh, it's obvious now! u=ln(x), du=(1/x), then I just input e^y and y and complete the problem.
I think my brain must have been fried from pulling an all-nighter getting my assignment completed; I've done more complex u-sub problems before with no complications.
I think I better start...
Yes; it's the fraction I'm having a problem with, though. I am not sure why, though. I've done them before. This semester though I haven't run into them often, and the ones I've seen were done in class as example problems (the teacher picks from his homework assignments).
I do have...
I need help with Iterated Integration. I'm trying to integrate the following equation:
∫ylnx/x from e^y to y for dx, y>0
(sorry about the messy equation; first time user)
I know how to integrate ln, but the fraction has me thrown for a loop. I tried U-substitution, but the equation kept...
