Problems for Elimination of Arbitrary Functions in one variable using Chain Rule -- Formation of PDE

In this video, we have solved the problems related to the elimination of an arbitrary function in one variable using the chain rule. In this previous video, we discussed the concept of chain rule procedure to solve partial differential equations by eliminating the functions.
I hope this video will be useful for all the students who are studying this topic in their current syllabus or preparing for any competitive exam.
The persons who have not watched the previous video related to this topic, I am giving you the link here
