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: 17,52,57,62,67,72,77,82,87,92,97,102 Determine the class size, the class limits and the true class limits

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

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

In Dr. Steve's math class, 12 students play the piano and 17 students play the guitar. If a total of 19 students play only one of these two instruments, how many students play both instruments?

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 .
