7.2 Integration as an Inverse Process of Differentiation. Integration is the inverse process of differentiation. Instead of differentiating a function, we are given the derivative of a function and asked to find its primitive, i.e., the original function. Such a process is called integration or anti differentiation.

SOLUTION. (i) Arranging the ages in ascending order, we get: 23, 26, 28, 32, 33, 35, 38, 40, 41, 54 We find that the age of the oldest teacher is 54 years and the age of the youngest teacher is 23 years. (ii) Range of the ages of the teachers = (54 – 23) years = 31 years. (iii) Mean age of the teachers.
