NettetI was able to find the correct answer by calculating the normal vector (using cross product) at each point on the surface parametrized: n → = ( − r) i → + ( − r) j → + ( r) k → And then I used polar coordinates to integrate the domain of the parametrized surface: ∫ 0 2 π ∫ 0 2 n → d r d θ = 3 ∫ 0 2 π ∫ 0 2 r d r d θ = 4 π 3 Nettet17. nov. 2024 · Another way to look at the polar double integral is to change the double integral in rectangular coordinates by substitution. When the function f is given in terms of x and y using x = rcosθ, y = rsinθ, and dA = rdrdθ changes it to ∬Rf(x, y)dA = ∬Rf(rcosθ, rsinθ)rdrdθ. Nettet17. des. 2024 · since, after introducing polar coordinates, this bound has all of the variables in itself, which makes it impossible to integrate over any of the variables i have, so i don't know how to solve this.
