Homework Statement
cylindrical coordinates: r=2cscƟ, give both rectangular and spherical cordinates
Homework Equations
I know this:
From rectangular to cylinder
z=z r2=x2+y2 tanƟ=y/x
From Cyl to rectangle
x=cosƟ y=sinƟ z=z
From cyl to spherical
Ɵ=Ɵ ρ2=x2+y2+z2 ɸ=sin-1r/ρ
From Spherical to cylindrical
Ɵ=Ɵ r=ρsinɸ z=ρcosɸ
The Attempt at a Solution
so far what I have is
r=2/sinƟ
can anyone please help me, I got stuck
