A signed distance function in 2D is more straightforward to reason about so we’ll cover it first. Additionally, it is helpful for font rendering in specific scenarios.

Graphs of quadratic functions can be used to solve equations. Example. Draw the graph of \(y = 2x^{2} + 2x – 4\) for values of –3 to 2. Use the graph to solve the equation \ ...

National 5; Working with the graphs of trigonometric functions Example. Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points.
