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 ...

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 ...

Trigonometric identities might seem like abstract mathematical concepts, but they're actually powerful problem-solving tools that can transform seemingly impossible equations into manageable solutions ...

Building a giant steel bale feeder is hard. Try it. Problem No. 1: Unless you live in ranch country, you probably don't even know what it's supposed to look like — regardless of whether you can build ...

This is an updated version of a story first published on May 5, 2024. For many high school students returning to class, it may seem like geometry and trigonometry were created by the Greeks as a form ...

Holy trinity of software. beware! Move over spreadsheet data base handler and word processor. Make room for the equation solver, the simulation/prediction program for those who live by the numbers.
