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 ...

Discovered in the 5 th century B.C. by none other than Pythagoras himself, the Pythagorean Theorem (a 2 + b 2 = c 2) lies at ...

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 pair also claim to have found five additional proofs using the same basic method, and leave these to the reader to work ...

In 2022, two high school students created a trigonometric proof of the Pythagorean Theorem—something that’s only ever been accomplished by a few professional mathematicians. Now, a new article ...
