Evaluate the composition of trigonometric functions by creating a right triangle. In this video we will evaluate the tangent by given the ratio for cosine. To do this we will use right triangle and ...

In this video I will cover how to evaluate the six trigonometric functions given a right triangle. We will find the missing side of the triangle using Pythagorean Theorem and then write the ratio for ...

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 ...
