As a tangent is a straight line it is described by an equation in the form \(y - b = m(x - a)\). You need both a point and the gradient to find its equation. You are usually given the point - it's ...

Learn how to solve trigonometric equations in Higher Maths involving multiple or compound angles and the wave function in degrees or radians.

Convert the degree values to radians to ensure proper calculation of the tangent values. Type *PI ()/180 immediately after the cell value that appears in the Function Argument's Number window.
