Spherical Coordinates Derivation

- In this video, I derive the equations for spherical coordinates, which is a useful coordinate system to evaluate triple integrals. Then, I show that the Jacobian when using spherical coordinates is rho^2 sin(phi). Enjoy!
Thank you so much!! No videos, or my teacher could've explained this as well as you!!.
Why do mathematicians and physicists swap theta and phi?
They also switch the x,y and z axis,
Because physicists are dumb
@@XanderGouws Ironically spherical coordinates are more useful in physics than math.
@@XanderGouws But we have biscuits....
@@aram9167 Not really
Theta is a circle with a HORIZONTAL line across it, it's Horizontal. Phi has VERTICLE line across the circle, so it's Verticle
WOOOOOOW, I’m gonna use that in my class now!!! 😱
Except physics uses the opposite convention
Thank you Dr. Peyam, I miss multi-variate calc. I like to go back to old class stuff to make sure I'm keeping it fresh in my head.
You are an amazing teacher.
who even decided to use rho instead of r for the radius anyway?
Stewart 🤮
I think rho was chosen so it isn't confused with r in cylindrical coordinates
Now we know that every sphere has radius of 2,7something.
Because this "rho" looks very similar to "e".
Multivariable calculus is the best calculus :D
That was one really nice video, Dr. Peyam, and I enjoyed it a lot, but the whole time while I was watching it I just was thinking about that very strange looking "ro". Ρ, ρ - this is "ro". Most of the time it's just P with a little tail. Maybe someone will think about that just like some kind of a nitpicking, but I truly want that a great math teacher, like you, just don't do this kind of "mistakes". Or maybe it's just in my part of the world we write it in this kind of manner
@@kyro1197 thanks, how I sad, maybe it's just not used in my part of the world. Good to know that ϱ - is ro too.
I just finished an electricity and magnetism class this semester, and as a math major I found it difficult at times to go from rho,theta, phi to r, phi, theta. It's pretty annoying.
Nice video! Is there a general rule how to get "Spherical" Coordinates in n dimensions?
Nice!!! ^^
That's not a rho, it's an e
