How It Works

How to Use the Trigonometry Solver

Trigonometry connects angles and ratios through a consistent set of identities. Our tool shows the connection at every step.

1

Input Your Trig Problem

Type in your equation, triangle, or identity to prove or evaluate.

2

Upload for Instant Analysis

Snap a photo of your worksheet or textbook question and the solver will read and process it automatically.

3

Step-by-Step Breakdown

See the identity, ratio, or unit circle value applied at each step, explained clearly, not just the final number.

What It Solves

What Our Trigonometry Solver Covers

From right triangle trig to graphing, this solver covers the full high school and college trigonometry curriculum.

Right Triangle Trig

Use SOH-CAH-TOA to find missing sides and angles in right triangles.

The Unit Circle

Find exact sine, cosine, and tangent values for common angles using the unit circle.

Trig Identities

Prove and simplify expressions using Pythagorean, sum, difference, and double-angle identities.

Graphing Trig Functions

Graph sine, cosine, and tangent functions, identifying amplitude, period, and phase shift.

Law of Sines & Cosines

Solve for missing sides or angles in any triangle, not just right triangles.

Inverse Trig Functions

Evaluate and interpret inverse sine, cosine, and tangent for a given ratio.
