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 ...

Watch this video to learn about solving trigonometric equations. Let's remind ourselves of what the sine graph looks like so that we can see how many solutions we should be expecting: Therefore ...

The app can also solve equations that use more complex formulas, like the trigonometric functions of sine, cosine and tangent. You need to include the equals sign (=) at the end no matter what.
