Hi, I'm teaching differential calculus and I'm trying to use sage plotting as much as I can.
For example, I want to show the graph of the derivative of |x|. What would be the best code to do this? For example, if I use: f(x) = abs(x+1) g = f.differentiate() show(plot(g(x),(-2,2)), xmin = -2,xmax = 1, ymin=-2,ymax=2) then the y-axis from -1 to 1 at x = -1 there is a big blue line, where there shouldn't be anything. So should I do something like: f(x) = abs(x+1) g = f.differentiate() p = plot(g(x),(-2,-1)) q = plot(g(x),(-1,2)) show(p+q, xmin = -2,xmax = 1, ymin=-2,ymax=2) Since I know the domain of definition of g?
