In Calculus II, we're learning about solids of revolutions and computing their volumes. I'm unsure when to apply the appropriate methods and how to make the correct partitions. Please tell me if my reasoning is correct: The disk/washer method is applied when your partitions are perpendicular...

You're right. Thank you.

In Calculus II, we're currently learning how to find the area of a bounded region using integration. My professor wants us to solve a problem where we're given a graph of two arbitrary functions, f(x) and g(x) and their intersection points, labeled (a,b) and (c,d) with nothing else given. I...

Thank you all for responding. I'm feeling a little better about the situation. I was worried that my lack of artistry might obfuscate some mathematical relationship, especially in three dimensions, but I believe I'll be okay. CrysPhys, thanks for your suggestion. That may be what I need...

I'm going to return to college starting Fall, 2019 as a physics major. In preparation, I've been going though various textbooks, studying the material and working the problems. The concepts I understand reasonably well. The problem? I'm horrible at drawing. I see some problems, especially in...

In a book on atmospheric physics I'm reading, the author begins a derivation by examining a fluid element of volume V = δxδyδz. In this context, what purpose is delta δ serving? Is it just a placeholder for an unspecified volume in the x, y, and z directions, or is it referring to an...

In lower-division physics classes, air resistance is usually ignored to make the mathematics of projectile motion easier to understand. When air resistance is included, it's often stated that at lower velocities, air resistance is proportional to the velocity of the object, Fair ∝ kv At...

The permittivity of free space, ε0, is usually given without any derivation or historical context as to how it was experimentally determined. Could you explain to me how the value of ε0 was first determined experimentally or provide a resource that gives such a derivation? Thanks!

Hi, I'm sorry if this question's been asked before but I was wondering how hands-on electrical engineering can be. Are there jobs where an EE can find themselves doing designing and getting to work with their hands? I find the theoretical stuff interesting as well as the more hands-on work.
