This type of curve is called a parabola and it is symmetrical. To draw the graph we need coordinates. We generate these coordinates by substituting values into the quadratic equation. A quadratic ...

The BrachiGraph project consists out of two parts, the hardware design for a servo-driven drawing arm (pen plotter) and software utilities (written in Python) that allow the drawing arm’s servos ...

Draw the graph of \(y = 3x - 1\). If you recognise this as a straight line then just choose two ‘easy’ values of \(x\), work out the corresponding values of \(y\) and plot those points.
