An equation of the form \(y = mx + c\) where \(m\) and \(c\) are numbers, gives a straight line when values of \(x\) and corresponding values of \(y\) are plotted on a grid. A straight line is a ...

Commutative algebra and graph theory are two vibrant areas of mathematics that have grown increasingly interrelated. At this interface, algebraic methods are applied to study combinatorial structures, ...

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 \) ...

This is a bank of randomized exercises for the CheckIt platform. The exercises align with learning outcomes for specific precalculus skills which, in the opinion of the bank's author, are "must have" ...

Some time ago I wanted to find a nice combination of sine waves that, when applied to the red, green, and blue components of a series of elements, would provide a nice gradient of colors. I wanted ...
