To evaluate a triple integral in cylindrical coordinates, use the iterated integral ∫θ=βθ=α∫r=g2(θ)r=g1(θ)∫u2(r,θ)z=u1(r,θ)f(r,θ,z)rdzdrdθ. To evaluate a triple integral in spherical coordinates, use the iterated integral ∫θ=βθ=α∫ρ=g2(θ)ρ=g1(θ)∫u2(r,θ)φ=u1(r,θ)f(ρ,θ,φ)ρ2sinφdφdρdθ.

**How do you convert cylindrical coordinates?**

To convert a point from spherical coordinates to cylindrical coordinates, use equations r=ρsinφ,θ=θ, and z=ρcosφ.

**How do you draw a sphere in spherical coordinates?**

A sphere that has the Cartesian equation x2 + y2 + z2 = c2 has the simple equation r = c in spherical coordinates.

### Can you use cylindrical coordinates for a sphere?

To convert a point from cylindrical coordinates to spherical coordinates, use equations ρ=√r2+z2,θ=θ, and φ=arccos(z√r2+z2).

**How to evaluate a triple integral in cylindrical coordinates?**

Evaluate a triple integral by changing to cylindrical coordinates. Evaluate a triple integral by changing to spherical coordinates. Earlier in this chapter we showed how to convert a double integral in rectangular coordinates into a double integral in polar coordinates in order to deal more conveniently with problems involving circular symmetry.

**Can a triple integral be defined in a cylindrical box?**

A cylindrical box described by cylindrical coordinates. If the function is continuous on and if is any sample point in the cylindrical subbox ( (Figure) ), then we can define the triple integral in cylindrical coordinates as the limit of a triple Riemann sum, provided the following limit exists:

#### What are the restrictions on the coordinates of an integral?

We also have the following restrictions on the coordinates. For our integrals we are going to restrict E E down to a spherical wedge. This will mean that we are going to take ranges for the variables as follows, Here is a quick sketch of a spherical wedge in which the lower limit for both ρ ρ and φ φ are zero for reference purposes.

**How is an iterated integral replaced in a cylindrical system?**

The iterated integral may be replaced equivalently by any one of the other five iterated integrals obtained by integrating with respect to the three variables in other orders. Cylindrical coordinate systems work well for solids that are symmetric around an axis, such as cylinders and cones.
