In this video we are going to explore an easy problem for evaluating the inverse of the tangent function and a hard problem ...

👉 Learn how to evaluate trigonometric functions using trigonometric identities. Trigonometric identities are equalities that ...

Solve the equation \(4\sin x^\circ - 3 = 0\), where \(0 \le x \textless 360\). From the graph of the function, we can see that we should be expecting 2 solutions: 1 solution between \(0^\circ\) and ...

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 ...
