This animation allows you to explore transforms of a complex variable such as $w = f(z)$. For example, the transform that displays whenever you refresh this page is $w = z^2$.
You can enter your own transforms by pressing 'edit' and editing the line that says $w = z^2$. You can also change colours and controls here. Try 'z useMouse', for example, if you would like to move z around with the mouse. Press 'Run' to exit the editor.
Normally, it's easier to drive the red $z$ point around with the keyboard ('z useKeys'). $w$ will then draw its moves in greeny blue. Both $z$ and $w$ lie at the base of their flag pointer. The flag tells you where they will jump to next when you press space.
Space: Jumps forward by the length of the flag pointer
Up Arrow: Increases the length of the pointer
Down Arrow: Decreases the length of the pointer
Left Arrow: Rotates the pointer left
Right Arrow: Rotates the pointer right

Meet the team
The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to embed rich mathematical tasks into everyday classroom practice.
