To convert a tangent value to an angle, use the inverse tangent function, also known as arctan or tan-1. This function takes the tangent value as input and returns the angle in radians. To convert to degrees, multiply the angle in radians by 180/π, use the degree mode on your calcul...
Example of how to calculate tangent of an angle If you want to find the tangent of a given angle, enter the degree into our tangent angle calculator or follow these steps: Identify the hypotenuse in your triangle. Usually, it is the longest side of the triangle. Measure the two sides bet...

The degree measure of angles is inherited from ancient Babylonians. There is another measure called the radian, which relates to another measure of the circle, the radius. One radian is the angle subtended at the center of a circle of radius {eq}r {/eq}, by an arc length of {eq}r ...
In general, the argument of a trigonometric function is considered to be a number, which may be regarded geometrically as the length of an arc or the radian measure of an angle. If the argument is regarded as an angle, the argument’s value can also be expressed in degree measure. For ...
The value of tan 90 degrees is undefined. The tangent of an angle is equal to the ratio of sine and cosine of the same angle. Learn how to derive the exact value of tan 90 at BYJU’S.

The value of tan 30 degrees can be calculated by constructing anangleof 30° with thex-axis, and then finding the coordinates of the corresponding point (0.866, 0.5) on theunit circle. The value of tan 30° is equal to the y-coordinate(0.5) divided by the x-coordinate (0.866). ∴ ...
which may be regarded geometrically as the length of an arc or the radian measure of an angle. If the argument is regarded as an angle, the argument’s value can also be expressed in degree measure. For acute angles ɸ (0 < ɸ < π/2), and only for such angles, the functions ...
