Okay it sounds like computer programming could be very beneficial. I have to take a python course for my major but nothing really after that. Would you recommend becoming familiar with java or c? I hear fortran is used a lot but is beginning to be phased out by c.

Hello all, I am currently an undergraduate in physics and have a significant amount of room in my schedule for classes. This is because I took mostly maths and general classes my freshman year, when deciding my major, and now will have to stay an extra half or full year to complete the core...

It is a partial derivative. You are allowing P,V,and T to very. So in partial derivatives you can take the derivative with respect to one variable and then the derivative with respect to the next variable and so on. The sum of this being your answer. That is how you get that equation...

Homework Statement A circular coil has 25 turns and a radius of 5 cm. It is at the equator, where the earth’s magnetic field is 0.7G north. Find the magnetic flux through the coil when its plane is (a) horizontal, (b) vertical with its axis pointing north, (c) vertical with its axis pointing...

Basically it means that it is decaying at a constant rate, thus allowing its decay to be defined by an exponential function. Think of it like this you start out with a large quantity and then divide it in half. Each time you divide it it is getting smaller and smaller at the same constant rate...

Hello Guss I am actually learning the same material in my class at this time. I'll see if I can make it a little clearer. The solenoid's magnetic field is a sum of all the fields produced by the individual turns. If you look at a cross section of a solenoid points very close to a turn...

When you see a three bar equal sign it means by definition it is equal to something. For instance you could say x=3 and that would be for a particular circumstance. But when you say for instance, Ampere's law, ∫B dot ds, that is by definition(three bar equal sign) equal to current enclosed...

Okay, so you can think of going from a single integral to double integral as instead of adding squares adding cubes from a limit. For instance a single integral should be 2D while a double integral is 3D. That made it a lot easier to understand. Thank you.

Homework Statement I am currently taking calc III and we have starting getting into double and triple integrals. I was wondering what you are actually doing when you take a double or triple integral? And what the difference is. I understand that you find area with a single integral and find...
