Understanding Trigonometric Functions
Trigonometric functions are mathematical functions that relate the angles of a right triangle to the lengths of its sides. The three most common trigonometric functions are sine, cosine, and tangent.
The sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse. The cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse.
The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
Trigonometric functions are used in a wide variety of applications, including navigation, surveying, and architecture.
Analyzing Trigonometric Functions for a Given Angle
To calculate the trigonometric functions for a given angle, you can use a calculator or a table of trigonometric functions.
The following table shows the values of the sine, cosine, and tangent functions for angles from 0° to 90°:
| Angle (°) | Sine | Cosine | Tangent |
|---|---|---|---|
| 0 | 0 | 1 | 0 |
| 30 | 1/2 | √3/2 | 1/√3 |
| 45 | √2/2 | √2/2 | 1 |
| 60 | √3/2 | 1/2 | √3 |
| 90 | 1 | 0 | undefined |
You can also use a graph to display the values of the trigonometric functions for different angles.
