WebYour intuition maybe f(x,y)dxdy=f(r,theta)drdtheta Not quite, it is because dxdy does not equal to drdtheta after r and theta is transformed into x and y, what can we do then? Scale it. We call the scaling factor the Jacobian. It is the determinant of a matrix called Jacobian matrix, usually denoted d(x,y)/d(r,theta), or J.

Derivation of Normal Distribution

WebI was watching a video which uses integration to show that the area under the standard normal distribution function is equal to 1. The function was squared which resulted in two variables x and y. This was converted to polar coordinated by x=r\cos\theta and y=r\sin\theta. The next line was dx\,dy=r\,dr\,d\theta.
