if anyone could send the solutions to tm0451 at hotmail dot com, that would be appreciated!

perhaps considering the limit as the mass of the cannon becomes very large will clarify things?

hi all, i'm in need of a little help with griffiths 9.5 (EM). the problem concerns a traveling wave of arbitrary shape on a string. the string consists of two strings with different mass densities tied together at z=0. given the arbitrary incoming wave, what are the transmitted and...

Hey all, I need some help with a multivalued complex integration problem. Evaluate the integral of (x^2-x^3)^-(1/3) from 0 to 1. I know you need to pick branches of the cube root function, and this will give you multiples of the integral which you can then equate to integrals along...

Yup, things have changed a little bit. We now have 8.01, which is standard mechanics in a lecture format, 8.01T, which is mechanics in a computer teaching laboratory environment, 8.01X, which is the aforementioned physics for poets/business majors, and 8.012, which was heavy duty indeed...

Never mind...got it.

Still not sure what to do...multiplying by the conjugate gives me something that doesn't seem so helpful to me, as I still can't find a comparison series. The limit comparison tests don't seem to be working either. Any more hints please?

Hey all, it's been a while since I've done series and I have a quick question. How would I show the convergence or divergence of \sum \left(\sqrt{n+1}-\sqrt{n}\right)? The ratio test is inconclusive I think, and I'm not sure how I would go about doing the root test. Or is there a series I...
