1.	Give a brief discription on Vectors along with the needed formulas .
Answer» BASIC FORMULAS and RESULTS of Vectors If →a=xˆi+yˆj+zˆk then the magnitude or length or norm or absolute value of →a is \|→a\|=a=√x2+y2+z2. A vector of unit magnitude is the unit vector. ... IMPORTANT unit vectors are ˆi,ˆj,ˆk, where ˆi=[1,0,0],ˆj=[0,1,0],ˆk=[0,0,1]
