Trig Function Calculator

Calculate all six trigonometric functions at once. Enter one angle, get sin, cos, tan, csc, sec, and cot.

Input

Unit

DegreesRadians

Angle (°)

Enter an angle to see all six trig functions

csc(θ) = 1/sin(θ)

sec(θ) = 1/cos(θ)

cot(θ) = 1/tan(θ) = cos(θ)/sin(θ)

tan(θ) = sin(θ)/cos(θ)

cot(θ) = cos(θ)/sin(θ)

sin²(θ) + cos²(θ) = 1

1 + tan²(θ) = sec²(θ)

1 + cot²(θ) = csc²(θ)

The six functions are sine, cosine, tangent, cosecant, secant, and cotangent. The last three are reciprocals of the first three.

tan and sec are undefined when cos = 0 (at 90°, 270°). csc and cot are undefined when sin = 0 (at 0°, 180°, 360°).

csc = 1/sin, sec = 1/cos, cot = 1/tan. Also tan = sin/cos and all satisfy the Pythagorean identities.
