What is the Trigonometry Calculator?
The Trigonometry Calculator is an all-inclusive mathematical tool that evaluates the six core trig functions (Sine, Cosine, Tangent, Cosecant, Secant, Cotangent) based on a single angular input.
How It Works (Formula)
Trigonometric functions define the relationship between the angles and side lengths of a right triangle. The calculator processes the angle through the Unit Circle algorithm to output the precise periodic ratios for all six functions simultaneously.
$$ \sin(\theta) = \frac{O}{H}, \quad \cos(\theta) = \frac{A}{H}, \quad \tan(\theta) = \frac{O}{A} $$

How to Use It
Select whether your input will be in Degrees or Radians. Enter your angle into the text box. The calculator will immediately evaluate the geometry and provide a neat table of all six trigonometric values.
