    Understanding Conditional Probabilities

    Homework Statement Suppose you have 3 nickels and 4 dimes in your right pocket and 2 nickels and a quarter in your left pocket. You pick a pocket at random and from it select a coin at random. If it is a nickel, what is the probability that it came from your right pocket? 2. The attempt at a...

    Solving the Integral present in Dirac's quantization of charge problem

    Yup. That does it. More specifically, 1-u^2 \geq 0 , since, for my problem, u \equiv cos(\theta) . Thanks, LCKurtz.

    Solving the Integral present in Dirac's quantization of charge problem

    Hi LCKurtz, I can't seem to get much further with that approach as I'm left with a (v+Du)dv in the numerator and can't see where to go from there.

    Solving the Integral present in Dirac's quantization of charge problem

    Homework Statement This problem involves an electric monopole placed at the origin and a magnetic monopole placed a distance D away, say arbitrarily, along the z-axis. I need to compute the angular momentum of the EM fieds: \vec{J_{field}} = \frac{1}{4\pi c}\int{d\tau \vec{r} \times...

    Proving vector calculus identities using the levi-civitia symbol

    Homework Statement Prove \nabla \bullet (\textbf{A} \times \textbf{B}) = \textbf{B} \bullet (\nabla \times \textbf{A}) - \textbf{A} \bullet (\nabla \times \textbf{B}) I'd like to prove this using the levi-civitia symbol: \epsilon_{ijk} and einstein-summation convention as practice and...
