24.05.2013 To find the magnitude of a vector first determine its horizontal and vertical components on their respective number lines around the origin. Next draw the horizontal and vertical components to plot the point where they intersect. Then draw a line from the origin to that point creating a vector triangle which is a right triangle. Finally use the Pythagorean theorem to calculate the triangles hypotenuse 73 %(87)As you can see the use of the absolute value bars for the magnitude of vectors is appropriate Magnitude like all other distances is always measured as a nonnegative value. The magnitude of a vector is the distance from the origin of a graph to its tip just as the absolute value of a number is the distance from 0 on a number line to that number.to find the magnitude which is 8.6. Apply the equation theta tan1(yx) to find the angle tan1(7.05.0) 54 degrees. However note that the angle must really be between 180 degrees and 270 degrees because both vector components are negative. That means you should add 180 degrees to 54 degrees giving you 234 degrees (the tangent of 234 degrees is also 7.05.0 7.05.0).

Vectors are used to describe the quangraphicies that define motion. The quangraphicies like momentum force velocity etc. have a fixed direction. The vector component of these quangraphicies give the direction as well as the magnitude.Autor Bindu SwethaMagnitude of a vector v with elements v1 v2 v3 vn is given by the equation v (v1 2 v2 2 v3 2 vn 2) You need to take the following steps to calculate the magnitude of a vector Take the product of the vector with itself using array multiplication (.). This produces a vector sv whose elements are squares of the elements of vector v.if r is a vector. norm(r) gives the magnitude only if the vector has values. If r is an array of vectors then the norm does not return the magnitude rather the norm
