Area between Curves
The
area between curves is given by the formulas below.
| Formula 1: |

|
| |
for a region bounded above and below by y = f(x) and y = g(x), and on the left and right by x = a and x = b.
|
| Formula 2: |

|
| |
for a region bounded left and right by x = f(y) and x = g(y), and above and below by y = c and y = d.
|
| Example 1:1 |
Find the area between y = x and y = x2 from x = 1 to x = 2.
|
| |

 |
| Example 2:1 |
Find the area between x = y + 3 and x = y2 from y = –1 to y = 1.
