Question

How to find maxima and minima using differentation?

Answer 1

for finding max and min by differentiation
just diff eq
assume given eq as f(x)
diff it once tat will be f'(x) equate it to zero u will get different value fr x
now do the diffrentiation again on f'(x) so will get f''(x)
now if f''(x)>0 the value u got fr x is minima and
substitute to get value
fr f''(x)<0 it will be maxima and do the above procedure
