Cosecant Calculator
Calculate the cosecant of an angle in degrees, radians or gradians. The cosecant is the reciprocal of the sine.
What is Cosecant?
Cosecant is the reciprocal of sine: csc(θ) = 1 / sin(θ). In a right triangle, it is the ratio of the hypotenuse to the opposite side.
Notable values: csc(30°) = 2, csc(45°) ≈ 1.4142, csc(90°) = 1. Cosecant is undefined where sin(θ) = 0, i.e. 0°, 180°, 360° and integer multiples of 180°.
Unit conversions: 1° = π/180 rad ≈ 0.01745 rad. 1 rad = 180°/π ≈ 57.296°. 400 gradians = 360°.
