## What are Cartesian coordinates used for?

Cartesian coordinates can be used not only to specify the location of points, but also to specify the coordinates of vectors. The Cartesian coordinates of two or three-dimensional vectors look just like those of points in the plane or three-dimensional space.

**What are cylindrical coordinates used for?**

Cylindrical coordinates are useful in connection with objects and phenomena that have some rotational symmetry about the longitudinal axis, such as water flow in a straight pipe with round cross-section, heat distribution in a metal cylinder, electromagnetic fields produced by an electric current in a long, straight …

**Where do we prefer spherical coordinates?**

Spherical coordinates are preferred over Cartesian and cylindrical coordinates when the geometry of the problem exhibits spherical symmetry. For example, in the Cartesian coordinate system, the surface of a sphere concentric with the origin requires all three coordinates (x, y, and z) to describe.

### What is the difference between Cartesian and polar coordinates?

This leads to an important difference between Cartesian coordinates and polar coordinates. In Cartesian coordinates there is exactly one set of coordinates for any given point. In polar coordinates there is literally an infinite number of coordinates for a given point.

**Can you use cylindrical coordinates for spheres?**

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

**What are Cartesian robots used for?**

Cartesian Robots are one of the most commonly used robot types for industrial applications and are often used for CNC machines and 3D printing.

#### How do we use coordinates in everyday life?

The latitude and longitude lines on maps of the Earth are an important example of spherical coordinates in real life. With the r-coordinate fixed at the radius of the Earth, the two-dimensional latitude and longitude plane is used to specify the location of different places on the surface of the Earth.

**Are cylindrical coordinates orthogonal?**

Cylindrical coordinate system is orthogonal : Cartesian coordinate system is length based, since dx, dy, dz are all lengths. However, in other curvilinear coordinate systems, such as cylindrical and spherical coordinate systems, some differential changes are not length based, such as dθ, dφ.

**Why do we use spherical coordinates?**

Spherical coordinates are useful in analyzing systems that have some degree of symmetry about a point, such as the volume of the space inside a domed stadium or wind speeds in a planet’s atmosphere. A sphere that has Cartesian equation x2+y2+z2=c2 has the simple equation ρ=c in spherical coordinates.

## Why we use spherical coordinate system?

Spherical coordinates determine the position of a point in three-dimensional space based on the distance ρ from the origin and two angles θ and ϕ. If one is familiar with polar coordinates, then the angle θ isn’t too difficult to understand as it is essentially the same as the angle θ from polar coordinates.

**What is the difference between spherical coordinates and cylindrical coordinates?**

Cylindrical coordinates are more straightforward to understand than spherical and are similar to the three dimensional Cartesian system (x,y,z). In this case, the orthogonal x-y plane is replaced by the polar plane and the vertical z-axis remains the same (see diagram).

**Is it possible to convert from Cartesian to spherical coordinates?**

In the same way as converting between Cartesian and polar or cylindrical coordinates, it is possible to convert between Cartesian and spherical coordinates: If you make ρ a constant, you have a sphere. If you make θ a constant, you have a vertical plane.

### What is the conversion between cylindrical and Cartesian systems?

The conversion between cylindrical and Cartesian systems is the same as for the polar system, with the addition of the z coordinate, which is the same for both: r 2 = x 2 + y 2, tan θ = y x and z = z x = r cos

**What is the application of the spherical coordinate system in real life?**

If you make r constant, you have a cylindrical surface. The spherical coordinate system is more complex. It is very unlikely that you will encounter it in day-to-day situations. It is primarily used in complex science and engineering applications. For example, electrical and gravitational fields show spherical symmetry.
