Double integral using polar coordinates

WebWe need to use substitution to convert this double integral to polar coordinates. The upper boundary for y can be used, we square that to get a relation for the radius. You can set that upper boundary, 2 x – x 2 is actually equal to y. See the following steps: y = 2 x – x 2 y 2 = 2 x – x 2 x 2 + y 2 = 2 x r 2 = 2 x r 2 = 2 r cos ( θ) r ... WebExample 1: Evaluate the integral. I = ∫ ∫ D ( x + y) d A. when D consists of all points ( x, y) such that. 0 ≤ y ≤ 9 − x 2, 0 ≤ x ≤ 3.

WebThe polar-coordinate change probably is a good choice, yes. The problem is to express r, along the vertical edge, as a function of θ. That vertical edge consists of points where x = 1, i.e., where r cos θ = 1. So r can be expressed as 1 / cos ( θ). That means that your integral becomes. ∫ θ = − π / 4 π / 4 ∫ r = 0 1 / cos ( θ) r ...
