How to find a unit vector u that has the same direction as vector a =

1.	How to find a unit vector u that has the same direction as vector a = 10i + 24j?
Answer» The unit vector uthat has the same direction as vector a = 10i + 24j is u is(5/13)i + (12/13)j. Vectors are very important concepts in mathematics, which have many applications in engineering and physics. They are used to calculate the trajectory of an object undergoing projectile motion, as well as the path to be followed by a rocket.
