—
Select function, enter angle, then click Calculate.
How to use
- Choose the trigonometric function (sin, cos, tan, cot, sec, csc, arcsin, etc.).
- Select angle mode Degrees or Radians.
- Enter the angle value (e.g., 30, 45, 1.57, etc.).
- Click Calculate – the result and step‑by‑step explanation appear instantly.
- Use Copy Result to copy the computed value.
- For inverse functions (arcsin, arccos, arctan), the input must be within the domain [-1, 1] for sin/cos.
- cot, sec, csc are defined as 1/tan, 1/cos, 1/sin. Tan, cot, sec, csc are undefined at certain angles (display error).
