S x^2(e^((x^3)+1)) I know I have to use integration by parts, and I'm guessing I should find the derivative of e^((x^3)+1), but I really have no idea where to start...

How do I find the integral for any integral of the type: f(x)g(x)dx I've looked every where, and the closest I've seen is integration by parts which is apparently for the integral of f(x)g'(x)dx, which, to my inexpert eyes, is a completely different integral than the first one Also, this...

Let's say I have the equation for a circle but don't know how to calculate its radius. How could I use integration to find its area?

m=3 is the second harmonic because when m=2 then it's a closed tube.

In a compass plot, the 0 degree point is the rightmost part of the plot. See attached: http://people.rit.edu/pnveme/pigf/TwoDGraphics/twod_dir_compass.gif

"Electromagnetic pumping is a non-invasive method of moving liquid used in situations where the moving parts of traditional pump are not practical. Pumping liquid metal is an example. Electromagnetic pumping involves applying an electric field and a magnetic field at the same time. Consider a...

OMG you're right. Thanks so much. How stupid of me. I got the formula (mv^2)/r confused with (mv^2)/2 Please be so kind as to assuage my severely bruised ego with anecdotes of any past careless mistakes you have made :redface:

1. A proton and an electron, with the same kinetic energies, enter a magnetic field and both attain circular orbits. What is the ratio of the radii of the orbits to each other? KE = qvB = (mv^2)/r --> r = mv/qB 3. We know both q values and both m values. The B value is...
