The online trigonometry simulations on this page will help you better understand the basics of trigonometry and its most important functions.

Trigonometry is a branch of mathematics that focuses on the study of the relationships between the angles and sides of triangles. In particular, we study trigonometric functions, which are mathematical functions that relate the angles of a triangle to the lengths of its sides.

The most common trigonometric functions are sine, cosine and tangent. These functions are defined in terms of an acute angle within a right triangle. The sine of an angle is equal to the length of the opposite side divided by the length of the hypotenuse, the cosine of an angle is equal to the length of the adjacent side divided by the length of the hypotenuse, and the tangent of an angle is equal to the length of the opposite side divided by the length of the adjacent side.

Trigonometry is also used to solve problems in other areas of mathematics, such as calculus and analytic geometry, as well as in fields such as physics, engineering and navigation.

## Trigonometry. Angle variation

This animation provides a representation of the variation of the sine, cosine and tangent as the angle changes.

## Trigonometry on the Ferris wheel

This animation provides a representation of the sine function. Notice how the height of the red cab is determined by the sine function.

## Trigonometry Units. Radians

This simulation allows to check how different angles are measured in radians.

## Trigonometry functions. Sine and cosine

With this simulation you can see how the sine and cosine functions are generated with the rotation of a segment.

## Trigonometric Tour

This simulation will take you through a tour of trigonometry using trigonometry using degrees or radians! Look for patterns in the values and in the graph when the value of theta is changed. Compare the graphs of sine, cosine, and tangent..
