Application of Differentiation


A rectangular sheet of tin 7cm x 5cm is to be made into a box without top, by cutting off squares from the corners and folding up the flaps. What should be the side of the square to be cut off so that the volume of the box is maximum ?

Vector Algebra

In our day to day life, we come across many queries such as - What is your height ? How should a football player hit the ball to give a pass to another player of his team? The possible answer to the first query may be 1.6m or 1.4m...- a quantity that involves only one value (magnitude) which is a real number. Such numbers are called scalars. However, an answer to the second query is a quantity (force) which involves muscular strength (magnitude) and direction (in which another player is positioned). Such quantities are called vectors. ie, A quantity that has magnitude as well direction is called a vector.
