I know parabola coordinate and that is z=X^2+Y^2 and I can use polar coordinate too.
Now I want to shift my Parabola PI/4 like what you see in picture please help me to find formula.
You don't have your axes labeled but that looks like a rotation of radians about the y-axis. Such a rotation can be done by multiplying by the matrix
And, of course, the reverse is just rotating through the negative angle so is multiplying by
How can I change write this one?
I try to draw it with MATLAB!
new x,y,z is
