This page covers the following topics:

1. Calculating area under a curve

The area bounded between two curves can be found by subtracting the lower function by the upper one and integrating between the limits.

# 1

Calculate the shaded area of the given graph.

# 2

Find the area between y = x³ + 3 and y = x + 1 between the points x = 1 and x = 2.

# 3

Use definite integrals to find the area between y = 2x + 10 and y = 2x + 4 between the points x = 5 and x = 2.

# 4

Evaluate the area between the curves y = −x + 9 and y = x² + 3 between the points x = 0 and x = 2.

# 5

Find the area between y = −x and y = x² − 8 between the points x = 0 and x = 2.
