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 ...

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 ...

A mathematician has uncovered a way of answering some of algebra's oldest problems. University of New South Wales Honorary Professor Norman Wildberger, has revealed a potentially game-changing ...

This study is an attempt to analyze students' construction of function based problem solving methods in introductory algebra. It claims that for functions to be a main concept for learning school ...

A UNSW Sydney mathematician has discovered a new method to tackle algebra's oldest challenge—solving higher polynomial equations. Polynomials are equations involving a variable raised to powers, such ...

Most people learned math as children by writing out problems on paper. This calculator app lets you do just that, but also lets you perform complex computations, all by writing numbers and symbols on ...

Since 2004, I have worked on PCMag’s hardware team, covering at various times printers, scanners, projectors, storage, and monitors. I currently focus my testing efforts on 3D printers, pro and ...
