Hello everyone. This is my first discussion, and I want to discuss the methods of finding the maximum and minimum value of a given function. I know of three important methods to do so, namely
AM GM HM Inequality
Maxima and Minima Concept from Calculus
Cauchy Schwarz Inequality (useful for trigonometric functions)
I would be glad to know if anyone has any other methods of finding the extremum values of a function. I am also interested to know/hear of problems related to such concepts.
