What is the formula for the cone coordinate?
or √x2+y2=ρsinϕ. (Given that 0≤ϕ≤π, we know that sinϕ≥0 and the positive square root is ρsinϕ.) If we divide by z=ρcosϕ, we obtain a formula for ϕ in terms of Cartesian coordinates √x2+y2z=tanϕ. where C=1/tanϕ, which is indeed the equation for a cone.
What are the limits for a cone in cylindrical coordinates?
In cylindrical coordinates, the cone is described by 0≤θ≤2π,0≤r≤1,r≤z≤1.
In cylindrical coordinates, the infinitesimal surface area is dA=sdθdz.
Using the straight line equation which gives s=Rh(h−z), I obtain A=πRh.
