# Tangent Calculator (tan)

command: tan

The calculator returns the tangent value of a given number. Tangent function is one of the most important trigonometric functions.

tan 2


Result:

tan 2
tan
(2) = -2.185039863261519


-2.185039863261519 is tan(2). The unit of arguments is radian, not degree. If you input multiple arguments, the calculator calculates at the same time and shows all the results.

tan 2 4 -1


Result:

tan 2 4 -1
tan
(2) = -2.185039863261519
(4) = 1.1578212823495775
(-1) = -1.5574077246549023


## Degree arguments

The default of angle unit is radian but you can input the degree angle using d suffix.

tan 45d 60d 135d 3.14159265
tan
(45°) = 0.9999999999999999
(60°) = 1.7320508075688767
(135°) = -1.0000000000000002
(3.14159265) = -3.5897930298416118e-09


45d means 45°. d suffix means the value is in degree.
