Radians and degrees are both units for measuring angles with respect to a circle. Convert radians to degrees by multiplying the number of radians by 180 and then dividing the result by pi. Express your final answer in de... More »

To convert degrees to radians, simply multiply the number of degrees by π /180°. Though pi can be converted into its decimal approximation 3.14, it is generally acceptable to leave it as "pi" without converting to decima... More »

A radian is a unit of angular measure widely used in many branches of mathematics and physics. One radian is equal to the measure of an angle at the center of a circle with an arc that is equal in length to the radius of... More »

A unit circle can help solve values for the tangent of angles 30 degrees, 45 degrees and 60 degrees. Tan (θ) = x/y, sin (θ) = y and cos (θ) = x. By substituting x and y, tan (θ) = sin (θ)/cos (θ). More »

The arc tangent (arctan) of 2 degrees is 63.43, while the arctan of 2 radians is 1.107. The function arctan(2) can also be described as the inverse tangent and is written as tan^-1. More »

The equation used to convert degrees to radians is rad = (deg x pi)/180, where rad stands for radians, deg is degrees and pi is equal to 3.142. Radians and degrees are ways to measure an angle in a circle. More »
