Evaluate sin, cos or tan of an angle in degrees or radians. Standard angles (multiples of 30° and 45°, or π/6, π/4, …) get exact values using reference angles and quadrant signs; others are given to 6 decimal places. The right-triangle solver finds the missing sides and angles from any two values using Pythagoras and SOH-CAH-TOA.
