GRAPHICAL ILLUSTRATIONS
RIGHT TRIANGLE
Cosine is the ratio of the adjacent side of a right triangle to the hypotenuse.
UNIT CIRCLE
In a unit circle, the cosine function is represented by the x-coordinate of the point corresponding to the given angle.
FUNCTION GRAPH
Cosine is a fundamental trigonometric function, complementing sine in many calculations. For a real angle between 0 and 90 degrees, the cosine of the angle is defined as the ratio of the length of the adjacent side to the hypotenuse in a right triangle.
The calculator above computes the cosine value of an angle given in degrees or radians. It also generates graphs that illustrate the cosine value of the angle. For angles within 0 to 90 degrees, it visualizes the cosine value on a right triangle; for angles ranging from -3000 to +3000 degrees, it depicts the cosine value on the coordinate system; and for any angle, it represents the cosine value on the unit circle.
