Well, I was unable to comprehend the teacher. Here is his rating: Mod note: link deleted He doesn't explain anything. He just talk bunch of crap and post it on to a PowerPoint. The worst part is that I will be getting him again this summer (bad luck huh). I guess my problem is that I can't...
Hey guys,
I am having issues with E&M. I am taking it again this summer and I am scared to death. Last time I took it, I wasn't able to withstand the load and drop out before the deadline. I am very good in Math, but the teachers are horrible.I was able to pass the first test with a horrible...
Ok here goes nothing,
I know from FTC, that g(x)=f'(x)
So in my case replace all the x with t and make f(t)= 0 to find the critical points
I get ((t²+15t+36)/(1+cos²(t)))=0 I found t=-12/-3
Next I take the f"(t) using the quotient rule to find my local max. I get...

Identical isolated conducting spheres 1 and 2 have equal charges q and are
separated by a distance r large compared to the diameters of the spheres. The electrostatic
force acting on sphere 2 due to sphere 1 is 3.10-6N. Suppose now, that the third identical sphere 3, having...
