Proportionality constants are written within the image: sin θ, cos θ, tan θ, where θ is the common measure of five acute angles. In mathematics , the trigonometric functions (also called circular functions , angle functions or goniometric functions [1] [2] ) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships between side lengths and angles of triangles.
