# Doubt from application of derivative

Expanding the integral and differentiate ,set it to zero and get the maxima or minima condition

i dnt think it will work i hve tried it before wrt to which u r going to diffrenciate...

**Sneha_2021**#13

if fx is monotonous functionin (a,b) then area bounded by y=f(x) x=a to x=b is minimum will occur at c=a+b/2...a nd b r limit of function..

**Aryan_2021**#15

Well I am not getting what u r saying : see how by a+b/2 minimizes area?

will not area be constant actually ??**Aryan_2021**#16

For explanation see this :

. and pls share your way Sneha , I am not getting that thing u r saying ( will.not area be actually constant )??**Aryan_2021**#18

Well the wanted area is easy to get in terms of inverse . u can try by f(x) as well Sneha but we want value of k , f inverse gives it directly . ( Share ur way Sneha )
