Now the integral can be solved just like any other integral. ∫π / 4 π / 6∫√3secθ cscθ rdrdθ = ∫π / 4 π / 6(3 2sec2θ − 1 2csc2θ)dθ = [3 2tanθ + 1 2cotθ]π 4 π 6 = 2 − √3. Example 3.4.4
Webthus dx dy = ∂ (x (r,θ), y (r,θ))/∂ (r,θ) dr dθ = r dr dθ just as with the chainrule df = f' (x) dx (and here the relation between df is also different from points to point as f' (x) depends on x. if it's a linear relation f (x) = mx+b it stays the same. df = m dx) But why do we assume that we are at distance r from the center?

WebMay 22, 2015 · That is, since I have z1dxdy (original cartesian function) = z2rdrdtheta (polar), shouldn't it be z1 = rz2 x drdtheta/dxdy? Where z1 is in x and y and z2 is simply the same function but with x and y directly subsituted with the appropriate rcostheta and rsintheta change.

But this is not correct! Remember what a double integral is doing: It chops up the region that we are integrating over into tiny pieces, and \redE {dA} dA represents the area of each one of those pieces. how to delete linkshell
