For my test on 8th March I require to know this. I don't understand how to find out maxima and minima.
Can you explin me the concept on Maxima and Minima?
take first derivative of the expression
equate this to zero and find the values of variable
take second derivative
substitute the values of variable
if the outcome for any value is positive then this is point of minima
and by putting this point of minima in given expression minimum value of the expression can be obtained
if the outcome for any value is negative then this is point of maxima
and by putting this point of maxima in given expression maximum value of the expression can be obtained
