Cosecant/Secant/Cotangent Calculator

About Cosecant/Secant/Cotangent Calculator

Welcome to the high‑precision Csc/Sec/Cot Calculator. This tool computes the reciprocal trigonometric functions — cosecant (csc = 1/sin), secant (sec = 1/cos), and cotangent (cot = 1/tan) — with adjustable precision from 1 to 1000 decimal places. It supports angles in degrees or radians, provides step‑by‑step explanations, and flags undefined angles clearly.

Key Features

• Three functions in one: csc(θ), sec(θ), and cot(θ).
• High precision: 1–1000 decimal places via arbitrary‑precision arithmetic.
• Units: Enter angles in degrees or radians with automatic conversion.
• Domain awareness: Identifies undefined cases (sin θ = 0 for csc/cot; cos θ = 0 for sec).
• Learning‑friendly: Step‑by‑step solution and unit circle visualization.
• Transparent details: Also shows sin(θ) and cos(θ) values used in computation.

How to Use

• Enter an angle and choose Degrees or Radians.
• Select a precision between 1 and 1000 (or use presets).
• Click Calculate to see csc, sec, and cot with full details.
• Undefined cases are explained and highlighted below the result.

Domain Notes

• csc(θ) is undefined when sin(θ)=0 → θ = k·π (k ∈ ℤ).
• sec(θ) is undefined when cos(θ)=0 → θ = π/2 + k·π (k ∈ ℤ).
• cot(θ) is undefined when sin(θ)=0 → θ = k·π (we compute cot = cos/sin for stability).
