The vector b can be expressed using unit vectors as follows:

b = bx * i + by * j + bz * k

Where bx, by and bz are the components of the vector b in the x, y and z directions respectively.

The unit vectors i, j and k are positive in the x, y and z directions respectively and have a magnitude of 1. They are often referred to as the standard basis vectors.

The vector b can be expressed in terms of the unit vectors i, j and k as:

b = bx * i + by * j + bz * k

The magnitude of the vector b is given by:

|b| = sqrt(bx^2 + by^2 + bz^2)

The direction cosines of the vector b are given by:

bx / |b| by / |b| bz / |b|

The vector b can be expressed in terms of its magnitude and direction cosines as:

b = |b| * (bx / |b|) * i + |b| * (by / |b|) * j + |b| * (bz / |b|) * k

The expression for the vector b in terms of its magnitude and direction cosines can be simplified to:

b = |b| * (cos(alpha)*i + cos(beta)*j + cos(gamma)*k)

Where alpha, beta and gamma are the angles between the vector b and the unit vectors i, j and k respectively.

Frequently Asked Questions

How to express a vector in terms of its component?

Typically, you would express a vector as its component vectors. For example, the x component of A is equal to 2.5 (since that is its length along the x axis). Likewise, they component of A written Ay, is 3.

What is the definition of a vector in math?

A vector is a quantity that has both magnitude, as well as direction.

How do I answer a vector problem in masteringphysics?

One way to answer vector problems in MasteringPhysics is by entering the vectors in terms of their component directions, i and y.

What is the unit vector of a vector?

A unit vector is a vector that has a length of 1. For any given vector, it’s possible to find the unit vector that has the same direction as the given vector.

How to find the unit vector of a graph?

The unit vector of a graph is simply the vector that has a magnitude of 1 and points in the same direction as the original vector. To find the unit vector, first find the magnitude of the vector, which can be found using the formula: Magnitude of vector a = √ (2 2 +5 2 + -9 2) = 10.488. Thus, the unit vector = (.191, .477, -.858), which has a length of 1 and is along the same direction as the original vector.
