Textbook Problem

Use a graph to give a rough estimate of the area of the region that lies beneath the given curve. Then find the exact area.

*y* = sec^{2}*x*, 0 ≤ *x* ≤ *π*/3

To determine

The area under the curve

Explanation

**Given information**:

The equation of curve is

The region lies between

Find *y* value using the curve function.

Substitute 0 for *x* in Equation (1)

Hence, the co-ordinates

Substitute 1 for *x* in Equation (1).

Hence, the co-ordinates

Similarly calculate for remaining *y* values and tabulate the results as in Table (1).

x | y |

0 | 1.00 |

30 | 1.32 |

60 | 4.00 |

Draw the diagram for the curve function

Show the diagram for the curve function

Refer to Figure (1).

The shaded portion

The area under the curve is calculated approximately by addition of
