WebRemember that your limits on θ become 0 to π/2. After swapping order of integration ( d θ dx to dx d θ), you can then do the substitution x = r cos θ, this time with θ the constant, so dx = cos θ dr. You will then notice that after you simplify the integrand, you will be left with. ∫ [ r ≥ 0] ∫ [0 ≤ θ < π/2] F ( r cos θ, r ... 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.
