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 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.
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.
With coordinates. A reference frame is chosen (a point of origin, and directions), and the position is described with two or three numbers (one for each dimension required), in relation to the point of origin.
Vectors can be represented graphically using arrows. The length of the arrow represents the magnitude of the vector, and the direction of the arrow represents the direction in which the vector is pointing. Vectors can also be represented by coordinates in a coordinate system.
Degree confluence points represent locations on Earth where integer degrees of latitude and longitude intersect. Vectors are used to represent the direction and magnitude of movement from one point to another, which can be calculated based on the coordinates of degree confluence points. Vectors can help determine the distance and direction needed to reach a specific degree confluence point from a given location.

Divide the vectors into horizontal and vertical components (or components in three dimensions). Add the components together for the different vectors. Convert the resultant vector back to polar coordinates, if need be. Note: Most scientific calculators have a special function to convert from polar coordinates (distance and angle) to rectangular coordinates (x and y coordinates), and back. If your calculator has such a function, using it will save you a lot of work.

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 matter what the angles are:* Express the vectors in Cartesian (rectangular) coordinates; in two dimensions, this would usually mean separating them into an x-component and a y-component. * Add the components of all the vectors. For example, the x-component of the resultant vector will be the sum of the x-components of all the other vectors. * If you so wish (or the teacher so wishes!), convert the resulting vector back into polar coordinates (i.e., distance and direction).
Vectors can be represented graphically using arrows. The length of the arrow represents the magnitude of the vector, and the direction of the arrow represents the direction in which the vector is pointing. Vectors can also be represented by coordinates in a coordinate system.
You do the dot product of the vectors by multiplying their corresponding coordinates and adding them up altogether. For instance: <1,2,3> ∙ <-3,4,-1> = 1(-3) + 2(4) + 3(-1) = -3 + 8 - 3 = 2
To multiply coordinates, you would multiply the x-coordinates together and then multiply the y-coordinates together. For example, if you have two points A(x1, y1) and B(x2, y2), the product of their coordinates would be (x1 * x2, y1 * y2). This operation is commonly used in geometry and linear algebra when scaling vectors or transforming points.
Degree confluence points represent locations on Earth where integer degrees of latitude and longitude intersect. Vectors are used to represent the direction and magnitude of movement from one point to another, which can be calculated based on the coordinates of degree confluence points. Vectors can help determine the distance and direction needed to reach a specific degree confluence point from a given location.
A disease which is carried and spread by an agent (animal or microorganism) is a vector spread disease. Eg. Mosquitoes are the vectors for malaria.
