Could you implement the two argument arctangent (atan2) function as well? Zoom in/out If you want some equation to specifically NOT work for some value m=n, then multiply something by (m-n)/(m-n) which gives 0/0 and thereby creates a hole in the function. Mathematical Functions Available In WeBWorK. Next lesson. There are huge benefits that are hard to foresee for example imagine a teacher making a video tutorial while typing equations instead of scribbling with hand, or a lecture where professor uses projector and desmos instead of a blackboard, typing is easier than writing and reading typed words is easier, everybody would be happy! Why is the iPad/iPhone app missing the integral and prime symbols which are available online? Currently, I'm using round(x*10^n)/10^n to round to "n" digits. When typing in a cube root (or odd root) function, be sure to include a coefficient, even if it is just 1. Practice Problems.
