Let f be a differentiable function on an interval I and let a I. Let f "(a) be continuous at a. Then i) 'a' is a point of local maxima if f '(a) = 0 and f "(a) < 0 ii) 'a' is a point of local minima if f '(a) = 0 and f "(a) > 0 iii) The test fails if f '(a) = 0 and f "(a) = 0. In th..

3 ) Ammonia molecule has an electronegative nitrogen atom bonded to three hydrogen atoms. Differences in electronegativity between nitrogen and hydrogen makes each hydrogen atom acquires positive charge. Thus, in the molecule, there is one negative site and three positive..
