What is the definition of vector How do you represent vectors How do you combine vectors?
A vector is a mathematical object that has both magnitude and direction, often represented as an arrow in a coordinate system. Vectors can be represented in component form, such as (\mathbf{v} = (v_x, v_y)) in 2D or (\mathbf{v} = (v_x, v_y, v_z)) in 3D. To combine vectors, you can use vector addition, which involves adding their corresponding components; for example, (\mathbf{u} + \mathbf{v} = (u_x + v_x, u_y + v_y)). Additionally, vectors can be combined using scalar multiplication, where each component of the vector is multiplied by a scalar value.

What are basis vectors in a transofrm?
Basis vectors are fundamental vectors in a vector space that define its structure and orientation. In the context of a transformation, they serve as the building blocks from which other vectors can be expressed as linear combinations. When a transformation is applied, the basis vectors are mapped to new vectors, allowing for the representation of the entire vector space in a transformed coordinate system. This concept is crucial in fields like linear algebra and computer graphics, where transformations are frequently utilized.
A vector of magnitude 3 cannot be added to a vector of magnitude 4 so the magnitude of the resultant is?
7
How will you multiply a vector by positive number?
A positive scalar multiplied by a vector, will only change the vector's magnitude, not the direction. A negative scalar multiplied by the vector will reverse the direction by 180°.
What is the difference between a Bitmap and a Vector image?
Bitmap graphics are made up of pixels of different colours whereas vector graphics are made up of objects. Bitmap graphics can be edited by individual pixels whereas vector graphics can be edited by individual objects.
Is Photoshop a raster or vector based program?
raster
When you combine two or more vectors the effect is called?
The effect is called vector addition. This process involves combining the magnitudes and directions of the individual vectors to determine the resulting vector.
Why can vectors be used to represent forces?
A vector is a quantity with magnitude and direction. Since force has magnitude and direction, it is a vector
What does the cross product represent in vector algebra?
The cross product in vector algebra represents a new vector that is perpendicular to the two original vectors being multiplied. It is used to find the direction of a vector resulting from the multiplication of two vectors.
Can any vector be represented by two other vectors that are right angels to each others?
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.
Why are some vectors pseudo vectors and some real vectors?
Answer: There are no "pseudo vectors" there are pseudo "rules". For example the right hand rule for vector multiplication. If you slip in the left hand rule then the vector becomes a pseudo vector under the right hand rule. Answer: A pseudo vector is one that changes direction when it is reflected. This affects all vectors that represent rotations, as well as, in general, vectors that are the result of a cross product.
What is the relationship between the components of a vector and the unit vectors in a given coordinate system?
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.
Can you give me examples of parallelogram and polygon method of representing vectors?
The parallelogram method involves placing two vectors such that they originate from the same point, forming a parallelogram, and the resultant vector is represented by the diagonal of this shape. For the polygon method, vectors are arranged in sequence, where the tail of one vector is placed at the head of the previous vector, and the resultant vector is drawn from the start of the first vector to the end of the last vector. Both methods visually depict how vectors combine to form a resultant vector.
Two or more vectors combine to form an?
The combination of two or more vectors results in a new vector known as the resultant vector. This resultant vector is found by adding or subtracting the individual vectors' magnitudes and directions.
What displacement vectors of 3 meters and 5 meters in the same direction combine to make a displacement vector?
The combined displacement vector would be 8 meters in the same direction as the individual vectors, as you simply add the magnitudes of the vectors together.
What is opposite to vector addition and subtraction?
The opposite of vector addition is vector subtraction, while the opposite of vector subtraction is vector addition. In vector addition, two vectors combine to form a resultant vector, whereas in vector subtraction, one vector is removed from another, resulting in a different vector. These operations are fundamental in vector mathematics and physics, illustrating how vectors can be combined or separated in different contexts.
How do you represent the 1000000 in vectors?
1000000 is a number and therefore it is a scalar. A scalar cannot be represented as a vector.
When adding vectors in one dimension what could the position of the head of the arrow represent?
When adding vectors in one dimension, the position of the head of the arrow represents the final displacement or position based on the individual vector components. It shows the combined effect of the vectors acting in the same direction or opposite directions.
