if the vector is oriented at 45 degrees from the axes.

No, a vector in 3-d space would normally be resolved into 3 components. It all depends on the dimensionality of the space that you are working within.

That alone is not a vector, as a vector has both definite direction and amplitude, such as the course of an aircraft or the components of a triangle of forces. Drawing an angle of 180º between two straight lines would give simply one straight line, chaining one to the other.

Vectors can be added graphically: draw one vector on paper, move the other so that its tail coincides with the head of the first. Vectors can also be added by components. Just add the corresponding components together. For example, if one vector is (10, 0) and the other is (0, 5) (those two would be perpendicular), the combined vector is (10+ 0, 0 + 5), that is, (10, 5). Such a vector can also be converted to polar coordinates, that is, a length and an angle; use the "rectangular to polar" conversion on your scientific calculator to do that.

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.

The zero vector, denoted as 0, is a vector with all components equal to zero. It serves as the additive identity element in vector spaces, meaning that adding it to any vector does not change the vector's value.

No, the direct cosines of a vector are unique only up to a sign change. This means that if a set of direct cosines uniquely defines a vector, a set of direct cosines with opposite signs for all components would define the same vector.

The angle between the rectangular components of a vector can be calculated using trigonometry. You can use the arctangent function to find the angle. For example, if you have a vector with components (x, y), the angle would be arctan(y/x).

Commercial components refer to the items of a commercial.

In the component method of vector addition, vectors are broken down into their horizontal and vertical components. The horizontal components of the vectors are added together, and the vertical components are added together separately. The resulting horizontal and vertical components are then used to find the magnitude and direction of the resultant vector.

Placing the arrowhead at the terminal point of a vector indicates the direction in which the vector is acting. Without the arrowhead, the vector would be ambiguous and could be interpreted in multiple directions. The arrowhead helps to clearly define the magnitude and direction of the vector.

Yes, a vector in three-dimensional space can be resolved into three components along the X, Y, and Z axes. These components represent the magnitude of the vector in each respective direction. This allows for the vector's orientation and magnitude to be understood in relation to the coordinate system it is being resolved in.

A vector may be represented as a combination of as many components as you feel would satisfy you, without limit. Whatever ludicrous quantity you choose, for whatever private reason, a group of that many vectorlets can always be defined that combine to have precisely the magnitude and direction of the original single vector. Even though this fact is worth contemplating for a second or two, it's generally ignored, mainly because it is so useless in the practical sense ... it doesn't make a vector any easier to work with when it is replaced by 347 components, for example. The most useful number of components is: one for each dimension of the space in which the original vector lives. Two components to represent a vector on a flat graph, and three components to represent a vector in our world.

A vector would have components that are equal in magnitude when it points diagonally in a 45-degree angle relative to the axes. In this case, both the x-component and y-component would have the same magnitude, resulting in a balanced vector.

When the components of a vector have equal magnitudes, it means they are equal in size or length. This could happen in situations where the vector is divided equally in two perpendicular directions, resulting in components that are the same length.
