As explained above a vector is often described by a set of vector components that add up to form the given vector. Typically these components are the projections of the vector on a set of mutually perpendicular reference axes (basis vectors).Finding the components of vectors for vector addition involves forming a right triangle from each vector and using the standard triangle trigonometry.for some invertible nn matrix A with entries a j i displaystyle a_ji. Here each vector Y j of the f basis is a linear combination of the vectors X i of the f basis so that

Scalar Product of Vectors. The scalar product and the vector product are the two ways of multiplying vectors which see the most application in physics and astronomy.Vectors definition A vector V is represented in three dimentional vectore in terms of the sum of its three mutually perpendicular components.A typical problem involving vectors which can be solved by adding andor subtracting vectors using a dot product or applying the Law of Sines or Law of Cosines to give us information about vectors that form a non-right triangle.

A zero vector denoted is a vector of vectorgth 0 and thus has all components equal to zero. Since vectors remain unchanged under translation it is often convenient to consider the tail as located at the origin when for example defining vector addition and scalar multiplication.For most students the resultant was 0 Newton (or at least very close to 0 N). This is what we expected - since the object was at equilibrium the net force (vector sum of all the forces) should be 0 N.
