Trigonometry Calculator
Free online trigonometry calculator. Enter an angle in degrees or radians to instantly compute exact values for sine, cosine, tangent, cosecant, secant, and cotangent.
The Six Core Trigonometric Functions
Trigonometry bridges the relationship between the lengths and angles of triangles, particularly right-angled triangles. Our highly accurate calculator maps the unit circle to provide exact ratios for any entered angle.
- Primary Functions (Sin, Cos, Tan): Evaluates the direct ratios of the Opposite, Adjacent, and Hypotenuse sides of a standard right triangle dynamically.
- Reciprocal Functions (Csc, Sec, Cot): Automatically calculates the mathematical inverse states of the primary functions, cleanly handling asymptotic geometric limits mathematically.
Frequently Asked Questions
What trig functions are supported?
This calculator evaluates all 6 core trigonometric boundaries: sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot).
Can I use radians?
Yes, you can easily toggle between entering angles in standard scalar Degrees or Pi-based Radians using the internal format switch.
What happens if I enter an angle where the tangent is undefined?
At bounds like 90 degrees or 270 degrees, tangent approaches infinity. Our calculator detects these vertical asymptotes and accurately reports the output as "Undefined" or "Infinity."
