In this video, I explain how to use Pythagorean identities to simplify trigonometric expressions. We focus on substituting 1-sin²θ with cos²θ to make the equation easier to work with, verifying the ...

Let's remind ourselves of what the sine graph looks like so that we can see how many solutions we should be expecting: Therefore, from the graph of the function, we can see that we should be expecting ...

👉 Learn how to solve trigonometric equations. There are various methods that can be used to evaluate trigonometric ...

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 ...
