Simultaneous equations like 𝒚 = 2𝒙 - 1 and 𝒚 = 𝒙 + 1 can be represented graphically. To solve the equations graphically, the two lines 𝒚 = 𝒙 + 1 and 𝒚 = 2𝒙 - 1 are drawn on the same diagram.

is an n ×n nonsingular matrix. Previously, a much smaller singularity criterion was used, which caused algebraic operations to be performed on values that were ...

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 ...

Several years ago, I wrote an article on using Elmer to solve complicated physics problems. Elmer has progressed quite a bit since then, so I thought it would be worth taking a fresh look at this ...
