The Total solution for NCERT class 6-12
Find the derivativeof the following functions from first principle
(i) x3 –27
(ii) (x – 1) (x – 2)
(iii) 1 / x2
(iv) x + 1 / x – 1
(i) Let f (x) = x3 –27
From first principle
(ii) Let f (x) = (x – 1) (x – 2)
(iii) Let f (x) = 1 / x2
From first principle, we get
(iv) Let f (x) = x + 1 / x – 1
