Does Khan academy ONLY teach math??

This has been fascinating, but I am still not sure what can I do with the Jacobian, I mean I have an idea, but there may be many uses I haven't thought about

why do you guys saves so many lives please tell me please may God be with you guys

So, I'm not entirely sure if there is or isn't another video covering this, but when you go from, say cartesian coordinates to polar coordinates in, say an integral, then you need to multiply with their jacobian determinants. this is usually found in books like Rottmanns formulae collection, but when finding these, does one then set up a jacobian determinant where f_1 is the cartesian and f_2 is the polar coordinates before the partial differrential?

Where can I find the subject of this video on Khan Academy?

This is awesome. If only you were my professor when I was in college.
