WebFormula. The magnitude of a vector, v = (x,y), is given by the square root of squares of the endpoints x and y. Thus, if the two components (x, y) of the vector v is known, its magnitude can be calculated by Pythagoras … WebFormula of Magnitude of a Vector. The magnitude of a vector can be calculated in two scenarios. In one case, the magnitude is calculated for a vector when its endpoint is at origin (0,0) while in the other case, the starting and ending point of the vector is at certain points (x 1, y 1) and (x 2, y 2) respectively. The formulas to claculate the ...
