I'm trying to plot the curve shown below on Matlab. $y= x \, \tan x$ and $x$ is in the range $(0, 4 \, \pi)$. The thing is
- I can't seem to multiply x with tan(x) without getting an error.
- I just need intersecting points between tan curve and circle (forget the cot curves in picture for now). Any suggestions? Figure
Does it have to be Matlab because Desmos does a pretty good job. See this graph.
