Maxima & Minima
Local maxima or minima
There is a maximum of f(x) at x = a if f’(a) = 0 and f”(a) is negative.
There is a minimum of f (x) at x = a, if f’(a) = 0 and f” (a) is positive.
To calculate maximum or minima, we find the point ‘a’ such that f’(a) = 0 and then decide
if it is maximum or minima by judging the sign of f”(a).
Global maxima & minima
We first find local maxima & minima & then calculate the value of ‘f’ at boundary points of
interval given eg. [a, b], we find f(a) & f(b) & compare it with the values of local maxima &
minima. The absolute maxima & minima can be decided then.
