Question


I want to sketch the parametric euqations lies on the cone, but the cone is so small and the lines are sparser than it should be.
parametric euqations is x=tcost, y=tsint, z=t and the euqation of the cone is z^2=x^2+y^2 my code looks like this t=linspace(...

How to solve 'vector must be the same length', 'functions behave unexpectedly' errors when graphing vector equation
The vector equation is r(t) = <3, t, 2-t^2> first of all . I tried t=linspace(-10,10); x=3; y=t; z=2-(t.^2); plot3(x,y,z)...

Question


I want to sketch one sheeted hyperboloid x^2-y^2+z^2=1 using meshgrid of MATLAB
my code looks like this. u=linspace(-10,10,50); v=linspace(0,2*pi,50); [u,v]=meshgrid(u,v); x=cosh(u).*cos(v); y=sinh(u...
