What is pigeonhole principle explain with example?

If there are n people who can shake hands with one another (where n > 1), the pigeonhole principle shows that there is always a pair of people who will shake hands with the same number of people. In this application of the principle, the ‘hole’ to which a person is assigned is the number of hands shaken by that person.

What is a Monovariant?

A monovariant is a property whose value only changes in one direction. It will either always increase or always decrease. In the above example, we could say that “The invariant property is that the last digit is always 0, hence it can never be 7!”

What is the invariance property?

In mathematics, an invariant is a property of a mathematical object (or a class of mathematical objects) which remains unchanged, after operations or transformations of a certain type are applied to the objects. Some important classes of transformations are defined by an invariant they leave unchanged.

How do you find invariant lines?

An invariant line of a transformation is one where every point on the line is mapped to a point on the line – possibly the same point. We can write that algebraically as M ⋅ x = X , where x = ( x m x + c ) and X = ( X m X + c ) .

What is the difference between covariant and contravariant vectors?

In differential geometry, the components of a vector relative to a basis of the tangent bundle are covariant if they change with the same linear transformation as a change of basis. They are contravariant if they change by the inverse transformation.

How do you find the midpoint of a 3d vector?

So the midpoint m of the segment joining x1, y1, z1 and x2, y2, z2 are x1+x2 over 2 y1+y2 over 2 and z1+z2 over 2 and that’s the midpoint formula.

What is a position vector in math?

In geometry, a position or position vector, also known as location vector or radius vector, is a Euclidean vector that represents the position of a point P in space in relation to an arbitrary reference origin O. Usually denoted x, r, or s, it corresponds to the straight line segment from O to P.
