The Area as a Double Integral Problem 1 Find the general formula as a double integral in rectangular coordinates that allows to find the area between the lines x = a, x = b and the curves y = g(x), y = f(x).
Problem 2
Find the general formula as a double integral in rectangular
coordinates that allows to find the area between the lines y
= c, y = d and the curves x =
Problem 3
Find the general formula as a double integral in polar
coordinates that allows to find the area between the lines
Problem 4
Find the general formula as a double integral in polar
coordinates that allows to find the area between the circles r
= a, r = b and the curves
Problem 5 The following graphics determine a series of curves in polar coordinates and their general designation. Using the general formulas of problems 4 or 5, find the area limited by the given curves.
