Cosecant Calculator

Use our free cosecant calculator to find the cosecant (csc) of any angle. Supports degrees and radians.

Math

Angle (θ)

Angle Unit

Formula

Cosecant is the reciprocal of sine. It relates an angle to the ratio of hypotenuse to opposite side.

csc(θ) = 1 / sin(θ)

Percentage: The percentage value you want to apply

Number: The original number or value

Result: The calculated result

How It Works

1Enter the angle value.
2Choose degrees or radians.
3Click Calculate to get csc(θ).

Examples

csc(30°)

1.θ=30°
2.sin(30°)=0.5
3.csc(30°)=1/0.5=2

Result: 2.0000000000

csc(90°)

1.θ=90°
2.sin(90°)=1
3.csc(90°)=1/1=1

Result: 1.0000000000

Frequently Asked Questions

Cosecant is the reciprocal of sine: csc(θ) = 1/sin(θ).

csc(θ) is undefined when sin(θ) = 0 (e.g., 0°, 180°).

csc(θ) ≤ -1 or csc(θ) ≥ 1.

csc(30°) = 2.

csc(θ) = 1/sin(θ) = hypotenuse/opposite.
