यही जज़्बा रहा तो मुश्किलों का हल भी निकलेगा
जमीं बंजर हुई तो क्या वहीं से जल भी निकलेगा
ना हो मायूस ना घबरा अंधेरों से मेरे साथी
इन्हीं रातों के दामन से सुनहरा कल भी निकलेगा…

Lecture - 9 Chapter 6 Application of Derivatives

In this lecture, I am discussing method to find approximate values of roots using derivatives and questions from NCERT Exercise 6.4

Questions discussed in this lecture:

NCERT EXERCISE 6.4 (Approximations)

Question 1. Using differentials, find the approximate value of each of the following up to 3 places of decimal.

\sqrt{25.3}

\sqrt{49.5}

\sqrt{0.6}

(0.009)^{\frac{1}{3}}

(0.999)^{\frac{1}{10}}

(15)^{\frac{1}{4}}

(26)^{\frac{1}{3}}

(255)^{\frac{1}{4}}

(82)^{\frac{1}{4}}

(401)^{\frac{1}{2}}

(0.0037)^{\frac{1}{2}}

(26.57)^{\frac{1}{3}}

(81.5)^{\frac{1}{4}}

(3.968)^{\frac{3}{2}}

(32.15)^{\frac{1}{5}}
