[PDF] 115 Cylinders and cylindrical coordinates - Academic Csuohio
The cylindrical form is useful for plotting surfaces obtained by rotating curves around the z axis Cylinders are the easiest example of this They are obtained by rotating lines of the form y=c about the x-axis Maple assumes that spherical coordinates will express rho as a function of theta and phi

Plotting a sphere in spherical coordinates is easy: specify the radius, perhaps 1 Maple plots functions in cylindrical coordinates with the cylinderplot command

Spherical Cylindrical Coordinates x = r cosθ r = √x2 + y2 y = r sinθ tan θ = y/x z = z z = z Spherical Coordinates x = ρsinφcosθ ρ = √x2 + y2 + z2 y = ρsinφsinθ
[PDF] Cylindrical and Spherical Coordinates - TAMU Math
In the cylindrical coordinate system, a point P in space is represented by the ordered triple (r, θ, z), where r and θ are polar coordinates of the projection of P onto
[PDF] Cylindrical and Spherical Coordinates Recall that in the plane it is
Cylindrical coordinates (r, θ, z) of a point P(x, y, z) are obtained by using polar coordinates (r, θ) of the projection in the x-y plane and leaving z unchanged: x = r cosθ, y = r sinθ, z = z To convert from rectangular to cylindrical coordinate we use: r2 = x2 + y2, tanθ = y x , z = z
