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).
