Class 12 | Differentiation | Lecture 18

Evaluate differentiation of y with respect to x : y=x^(4)+12x

Find the differential equation of system of cocentric circles with centre (1,2)

The class marks of a distribution are 12, 18, 24, 30. Find the class interval.

The starting value of the model class of a distribution is 20. The frequency of the model class is 18. The frequencies of the classes preceeding and succeeding are 8,10 and the width of the model class is 5, then mode is

Use differentials to find the approximate value of (17/18)^(1/4)

While calculating mode the following observation are found. Lower limit of modal class =40, frequency of modal class =20, frequency of previous class =12 , frequency of preceding class =11 and width of the class =10, find mode .
