Trigonometry is the branch of math that studies triangles, with a particular focus on the relationships between angles and the lengths of corresponding sides. Interestingly enough, the trigonometric ...

Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points. Working with trigonometric relationships in degrees Trigonometric functions can ...

Many students think they've solved a trig equation when they get one answer (one size of angle \(x^\circ\)). However there's often more than one answer expected so be aware of this. Let's remind ...
