Express the polar equation \(r=\cos 2\theta\) in rectangular coordinates. Find the maximum height above the \(x\)-axis of the cardioid \(r=1+\cos \theta\text{.}\) Sketch the graph of the curve whose ...

The answer: polar coordinates. Yes, you thought they were ... Here is the code with a plot of the angular value of the position as a function of time. Feel free to edit it and rerun it.

His tests open up some interesting possibilities in the world of blinkey LED stuff, including a polar coordinate display ... This makes plotting circles easier, but it also opens this display ...

This is achieved with a pair of NEMA 17 stepper motors, set up in a polar coordinate fashion. One stepper motor controls the angle, while another motor controls the marble’s distance from the ...
