but can u show me how did u do it :) please
A vector is a mathematical object that has both magnitude (size) and direction. It is commonly represented as an arrow pointing in a specific direction, with the length of the arrow representing the magnitude of the vector.
Unlike a vector, a scalar only has magnitude and no direction. Scalars are represented by a single value, while vectors have both magnitude and direction.
Vectors have many applications in physics, engineering, and computer graphics. They are used to represent forces, velocities, and displacements in physical systems, as well as in 3D modeling and animation.
Vectors can be added and subtracted using the parallelogram law or the head-to-tail method. In both methods, the components of the vectors are added or subtracted to determine the resultant vector.
Yes, vectors can have negative magnitudes. This indicates that the vector is pointing in the opposite direction of its positive counterpart. For example, a vector with a magnitude of -5 would be the same as a vector with a magnitude of 5, but pointing in the opposite direction.
