Resource Description

Trigonometry equations, especially the general solution, are difficult for many students to grasp. This presentation demonstrates in detail with animation and colour how to solve trigonometry equations. It includes the following topics:

– Methods to solve trigonometry equations

– Solving of trigonometric equations with a calculator

– Solving of trigonometric equations with special angles

– The general solution

– More complex equations with the general solution

– Equations with sin x = +- sin x, cos x = +- cos x, tan x = +- tan x

– Equations with a sin x = b cos x

– Equations with sin A = +- cos B

– Quadratic equations

– Equations with tan x, sin x and/or cos x

Each topic is explained first, then followed by examples with step-by-step solutions.
