INFORMATION

Sine is one of the most fundamental trigonometric functions. For a real angle between 0 and 90 degrees, the sine of the angle is the ratio of the length of the opposite side to the hypotenuse in a right triangle.

The above calculator computes the sine value of an angle given in degrees or radians. Additionally, it draws graphs representing the sine value of the angle. For angles between 0 and 90 degrees, it shows the sine value on a right triangle; for values between -3000 and +3000 degrees, it displays the sine value on the coordinate system; and for all angles, it represents the sine value on the unit circle.
