## Best explanation to understand and solve the chain rule problems.

Chain problems are one of the most valuable and essential part of arithmetic aptitude. it is simple and well-to-do section because students are got good marks from this section.

Chain problem is the significant topic for Numerous company interviews, bank exams and competitive exams like SBI PO, IBPS, INDIAN RAILWAYS.

The chain rule is a formula to calculate the derivative composition of functions.

Look down here, we equip the formula for the chain rule problems, chain issues shortcuts, chain rule example problems in aptitude, chain management tricks.

So, this will help you to positively face competitive exams. By having continous practice, you will improve your capacity and also you can develop your speed in problem solving.

### What is chain problem

A chain analysis is a technique designed to help a person understand the function of a particular behavior.

During a chain analysis of a particular problem behavior (for example, deliberate self-harm), a person tries to uncover all the factors that led up to that behavior.

### Formula for chain rule problems

Chain rule formula for computing the derivative of the composition of a two or more functions.

dy/dx = dy/du . du/dx

Few things  to solve chain poblems

Direct proportion – Two quantities are said to be directly proportional, if on the increase (or decrease) of the one, the other increases (or decreases) to the same extent.

Eg. Cost is directly proportional to the number of articles. (More Articles, More Cost)

Indirect proportion – Two quantities are said to be indirectly proportional, if on the increase of the one, the orther decreases to the same extent and vice-versa.

Eg. The time taken by a car is covering a certain distance is inversely proportional to the speed of the car. (More speed, Less is the time taken to cover a distance.)

Note : In solving problems by chain rule, we compare every item with the term to be found out.
