The spherical to cartesian unit vectors are used to convert coordinates between spherical and cartesian systems. They are denoted as ( hatr ), ( hattheta ), and ( hatphi ), representing the radial, azimuthal, and polar directions respectively.
In spherical coordinates, unit vectors are derived by taking the partial derivatives of the position vector with respect to the spherical coordinates (r, , ) and normalizing them to have a magnitude of 1. This process involves using trigonometric functions and the chain rule to find the components of the unit vectors in the radial, azimuthal, and polar directions.
The mathematical formula for calculating the spherical dot product between two vectors in three-dimensional space is: A B A B cos() where A and B are the two vectors, A and B are their magnitudes, and is the angle between them.
In a given coordinate system, the components of a vector represent its magnitude and direction along each axis. Unit vectors are vectors with a magnitude of 1 that point along each axis. The relationship between the components of a vector and the unit vectors is that the components of a vector can be expressed as a combination of the unit vectors multiplied by their respective magnitudes.
A unit vector is a vector with a magnitude of 1. It is often used to indicate direction without influencing the scale of a vector. Unit vectors are important in mathematics, physics, and engineering for simplifying calculations involving vectors.
Basis vectors in a transform represent the directions in which the coordinate system is defined. They are typically orthogonal (perpendicular) to each other and have unit length. These basis vectors serve as building blocks to represent any vector in the space.
They are unit vectors in the positive directions of the x and y axes.

Unit vectors are perpendicular. Their dot product is zero. That means that no unit vector has any component that is parallel to another unit vector.
Yes. This is the basis of cartesian vector notation. With cartesian coordinates, vectors in 2D are represented by two vectors, those in 3D are represented by three. Vectors are generally represented by three vectors, but even if the vector was not in an axial plane, it would be possible to represent the vector as the sum of two vectors at right angles to eachother.
No. Their magnitudes are equal (that's why they're "unit" vectors), but their directions are different.
In real life unit vectors are used for directions, e.g east, north and up(zenith). The unit vector specifies the direction. Gyroscopes maintain a direction and keep things level. Whenever and where ever location is important, unit vectors are a part of real life. Whenever directions are important in your real life, then unit vectors are important. If everything was confined to move along a straight line, then unit vectors would not be important. If you can move in a plane, then unit vectors are important. Moving in space, unit vectors are more important. cars, ships and planes all move in space. Controlling and tracking these all involve unit vectors.

Yes. There are, in fact, an infinite number of other bases in which to express a spacial vector. The rectangular coordinate basis (or Cartesian basis) is the set of unit vectors composed of a vector x pointing in an arbitrary direction from an arbitrarily chosen origin, a vector y perpendicular to x, and a vector z which is mutually perpendicular to both x and y in a direction dictated by the right-hand rule (x×y).Another common basis is the spherical polar basis composed of the unit vectors ρ, φ, and θ where ρ points from an arbitrarily chosen origin towards the point in space one wishes to specify, φ is perpendicular to ρ, and θ is defined as φ×ρ.There are an infinite number of other bases by which one can specify a point in space. The reason that bases such as the Cartesian basis and the spherical polar basis are seen so commonly is because they are simple and intuitive.

A unit vector is a vector whose magnitude is one. Vectors can have magnitudes that are bigger or smaller than one so they would not be unit vectors.
Yes., and their being along the coordinate axes does not change the answer.Consider the vectors: i, -i and j where i is the unit vector along the x axis and j along the y axis. The resultant of the three is j.
