When r = 0 then the angle can have any value.
When r > 0 then angles x and x+2kπ are the same for all integer values of k
The point whose Cartesian coordinates are (2, 0) has the polar coordinates R = 2, Θ = 0 .
The trigonometric formula or the polar coordinate form is x = a + r*cosΦ y = b + r*sinΦ where 0 ≤ Φ < 360 deg.
What are polar coordinates of (√2, 1)? Solution: Here we need to convert from rectangular coordinates to polar coordinates: P = (x, y) = (r, θ) r = ± √(x^2 + y^2); tan θ = y/x or θ = arc tan (y/x) So we have: P = (√2, 1) r = ± √[(√2)^2 + 1^2] = ± √3 θ = arc tan (y/x) = arc tan (1/√2) = arc tan (√2/2) ≈ 35.3°, which is one possible value of the angle. (√2, 1) is in the Quadrant I. If θ = 35.3°, then the point is in the terminal ray, and so r = √3. Therefore polar coordinates are (√3, 35.3°). Another possible pair of polar coordinates of the same point is (-√3, 215.3°) (180° + 35.3° = 215.3°). Edit: Note the negative in the r value.

account for the fact that some covalent bonds are polar while other are non-polar
The length of a straight line from a point then and second the angle
The definition of a spherical coordinate system is a coordinate system for 3D space where the position of a point is specified by three separate numbers. These three numbers are the radial distance, polar angle, and azimuth angle.
SeI4 is polar.When a compound hasno lone pairs2 lone pairs and 4 atoms4 lone pairs and 2 atoms3 lone pairs and 2 atomsit is non-polar. All others are polar.
Some problems are easier to solve using polar coordinates, others using Cartesian coordinates.
A Coordinate Covalent Bond is when one atom donates both of the electrons that will be shared between two atoms to form a bond. When two pairs of electrons are involved, it is never unequal.
no because in order to be classified as polar you must have lone pairs. So that would be a contradiction. I assume so
Because when the bond has formed the electrons moves to one side so it is polar.
NI3 is a polar molecule, one must remember that the lone pairs will skew the electron geometry.

You do not have to. You could use polar coordinates, if you prefer.
As a mathematical question this would refer to a choice of normally one of two popular coordinate systems, the Cartesian and the polar.
PBr5 is non-polar because it is a trigonal bipyramid with no unbound pairs.
