F(y) is our version of the constant of integration c because (due to the partial derivative) we had y as a fixed parameter that we know is really a variable.

Images. • using polar coordinates 1. F(x, y) dy dx x correct:

We can calculate the area ex.5. It's always best to sketch the curve before finding areas under. So now we need to discover f(y).

46 sketch the region of integration and change the order of integration

F(x, y) dy dx x correct: We investigate the integration limits and relate them to the 2d region of integration in. Dx, dy, x, y, etc added. Y = 4 cos 2x, y = 4 − 4 cos 2x, 0 ≤ x ≤ π/2.
