Math teachers have stymied students for hundreds of years by sticking goats in strangely shaped fields. Learn why one grazing goat problem has stumped mathematicians for more than a century. If you’ve ...

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 \(5\sin 2x^\circ + 7\cos x^\circ = 0\) for \(0^\circ \le x^\circ \le 360^\circ\) Which gives us solutions of \(90^\circ ,224.4^\circ ,270^\circ ,315.6^\circ\) There are two more ...

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 ...
