Explanation:

How to find local Maxima and Minima?

#y=f(x)# Then
Find the first derivative. #dy/dx#.
Equate it with zero and solve it for #x#
You will get a value for #x#

At that Value of #x# the slope of the curve is zero.

To find whether a maximum or minimum at that point, find the second derivative #(d^2y)/(dx^2)#

Substitute the value of #x# in that function,

If #(d^2y)/(dx^2)>0# There is a local minimum
If #(d^2y)/(dx^2)<0# There is a local maximum
