Trigonometry reference
Trigonometry studies relationships between angles and side lengths of triangles. Use this tool to evaluate sin, cos, tan, sec, csc, cot and their inverses. Generate tables for common angles and export as CSV.

Notes
When unit is Degrees, input angles are interpreted as degrees for trig functions and inverse trig returns degrees. Inverse mode will auto-suggest sensible input ranges (e.g. [-1,1] for asin/acos). For expressions with multiple variables or advanced functions, use math.js-compatible syntax (e.g. sin(x) + cos(x/2)).
