Trigonometry
Sine Calculator
Calculates the sine of an angle entered in degrees, returning a value between −1 and 1. Use it when solving right triangles, decomposing vector components, modeling waves, or working through trigonometry homework.

Trigonometry
Tangent Calculator
Calculates the tangent of an angle entered in degrees, representing the ratio of opposite to adjacent in a right triangle (or rise/run for a slope). Use it when finding the slope of a line, sizing roof pitch, or measuring height from a known horizontal distance.
