I'm new to Laplace and having slight difficulty with what looks like an obvious equation. I can do basic first and second order equations. Why is it that the seemingly easy equations are always the ones to stump you? Homework Statement \frac{dy}{dx}=-y y=2, x=0, y_{0}=2 Homework...

I guessed they weren't decimals. Hmm...this seems a lot more complicated than it looks. I must be missing something pretty fundamental to be this lost. Edit: Oh, now I've seen your edit I was understanding it perfectly well. I just got confused again. Sorry. Edit II: Sorry, should that...

I follow you up until the last equation, but I'm at a loss as to where you got those figures from. Edit: Unless that first 4 is supposed to be 3? But even then, is there a mathematical process I am missing for the final 4?

Hi I'm electrically-biassed, and we had a maths exam that was for both electrical and mechanical students. The last question on the paper was separated into two; one for electrical, one for mechanical. I did the electrical question (all about mean and RMS of an instantaneous voltage,)...

This is an enquiry into whether something is possible, so the numbers might be rubbish to work with. If I apply a voltage of v=25sin(wt+0.2rads) to a circuit, with a resultant current of i=15sin(wt-0.5rads), can I work out all three sides of a power triangle? I've been working on it for...
