👉 Learn how to solve equations using half-angle identities. To do this we will replace every trig function with half angles ...

In this video I will show you how to solve a trigonometric equation using the double angle for cosine. When applying the ...

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 ...

Let’s keep things simple – this is basic math. Nothing scary. Just everyday calculations, a bit of geometry, some number patterns, and the kind of stuff you definitely learned in school at some point.
