448 Three Dimensions Example 12.16 Find an equation for the sphere of radius 2 in spherical coordinates. Solution. If we start with the Cartesian equation of the sphere and substitute, we get the spherical equation: x 2 + y 2 + z 2 = 2 2 ρ 2 sin 2 φ cos 2 θ + ρ 2 sin 2 φ sin 2 θ + ρ 2 cos 2 φ = 2 2 ρ 2 sin 2 φ(cos 2 θ + sin 2 θ)+ρ 2 cos 2 φ = 2 2 ρ 2 sin 2 φ + ρ 2 cos 2 φ = 2 2 ρ 2 (sin 2 φ + cos 2 φ)=2 2 ρ 2 = 2 2 ρ = 2 Therefore, in spherical coordinates, a sphere of radius 2 is expressed ρ = 2. ♣ Although not as simple as with cylindrical coordinates, we can use spherical coordinates to describe the equation of a cylinder. Example 12.17: Cylinder Equation in Spherical Coordinates Find an equation for the cylinder x 2 + y 2 = 4 in spherical coordinates. Solution. Proceeding as in the previous example: x 2 + y 2 = 4 ρ 2 sin 2 φ cos 2 θ + ρ 2 sin 2 φ sin 2 θ = 4 ρ 2 sin 2 φ(cos 2 θ + sin 2 θ)=4 ρ 2 sin 2 φ = 4 ρ sinφ = 2 ρ = 2 sinφ ♣ Exercises for 12.6 Exercise 12.6.1 Convert the following points in rectangular coordinates to cylindrical and spherical coordinates: (a) (1,1,1) (b) (7,−7,5)

Exercise 12.6.3 Find an equation for the yz-plane in cylindrical coordinates. Exercise 12.6.4 Find an equation equivalent to x 2 + y 2 + 2z 2 + 2z − 5 = 0 in cylindrical coordinates. Exercise 12.6.5 Suppose the curve z = e −x2 in the xz-plane is rotated around the z-axis. Find an equation for the resulting surface in cylindrical coordinates. Exercise 12.6.6 Suppose the curve z = x in the xz-plane is rotated around the z-axis. Find an equation for the resulting surface in cylindrical coordinates. Exercise 12.6.7 Find an equation for the plane y = 0 in spherical coordinates. Exercise 12.6.8 Find an equation for the plane z = 1 in spherical coordinates. Exercise 12.6.9 Find an equation for the sphere with radius 1 and center at (0,1,0) in spherical coordinates. Exercise 12.6.10 Suppose the curve z = x in the xz-plane is rotated around the z-axis. Find an equation for the resulting surface in spherical coordinates. Exercise 12.6.11 Plot the polar equations r = sinθ and r = cosθ and comment on their similarities. (If you get stuck on how to plot these, you can multiply both sides of each equation by r and convert back to rectangular coordinates). Exercise 12.6.12 Extend Exercises 12.6.6 and 12.6.10 by rotating the curve z = mx around the z-axis and converting to both cylindrical and spherical coordinates. Exercise 12.6.13 Convert the spherical formula ρ = sinθ sinφ to rectangular coordinates and describe the surface defined by the formula (Hint: multiply both sides by ρ.) Exercise 12.6.14 We can describe points in the first octant by x > 0, y> 0 and z > 0. Give similar inequalities for the first octant in cylindrical and spherical coordinates.
