#### About 12 Maths Exercise 6.2

Class 12 Maths Exercise 6.2 is based on the concept whether a function is INCREASING or DECREASING in a given range. If the first derivative (as we have studies in Rate of Change Exercise 6.1) is positive in the given interval, the function is increasing but if it is negative, the function is decreasing. In case of Trigonometric Functions, we have to check the quadrant in which the function lies.

If for the increasing value of x, y is also increasing, the function is said to be increasing function. If the value of y is decreasing for increasing value of x, the function is said to be decreasing. For example: sin x is a increasing function in first quadrant but cos x is a decreasing function.
