Trigonometry Pro

Trigonometry Pro is the essential toolkit for students, engineers, and anyone who works with triangles and angles. Solve any triangle — instantly Enter any two known values and let the app calculate the rest. Whether you know two sides, one side and an angle, or any other combination, Trigonometry Pro finds the complete solution. Right Triangle Calculator • Solve using any two known values: sides (a, b, c) or angles (α, β) • Uses sine, cosine, tangent, and the Pythagorean theorem • Clearly shows which formula was applied **General Triangle Calculator** • Supports all cases: SAS, ASA, SSA, AAS, and SSS • Uses the Law of Sines and the Law of Cosines • Automatically detects and handles the SSA ambiguous case — shows both solutions when two valid triangles exist Theory & Learning • Animated Pythagorean proof — watch a² + b² = c² come to life step by step • Interactive unit circle — explore sine, cosine, and tangent at any angle • Right triangle reference with all key formulas Settings • Works in degrees or radians — switch instantly in Settings • Adjustable decimal precision (2–6 places) • Calculation history to review your recent work • Share results directly from the app Trigonometry Pro is built for iOS 26 with a pure SwiftUI interface and beautiful Liquid Glass design - Powerful, elegant trigonometry.
