## Chapter – 12

__Derivatives__

The concept of derivatives is a fundamental topic in calculus. A derivative represents the rate of change of a function with respect to its variable. If is a function of , the derivative of with respect to is denoted by or . It is defined as:

In simpler terms, the derivative measures how a function’s output changes as its input changes. For instance, if represents the position of an object at time , then gives the object’s velocity at time .

### Derivative Rules

Key derivative rules covered in Class 12 include:

**Power Rule:**For any real number , Sum and**Difference Rule:**If and are two functions, then**Product Rule:**If and are two functions, then**Quotient Rule:**If and are two functions, then**Chain Rule:**For composite functions, if , then

### Derivatives of Hyperbolic Functions

Hyperbolic functions, such as , , , and their inverses, have specific derivative rules:

### Higher Order Derivatives

Higher-order derivatives refer to the derivatives of derivatives. For example, the second derivative of a function is denoted by or , which measures the rate of change of the rate of change (acceleration, in physical terms).

### Logarithmic Differentiation

Logarithmic differentiation is a technique used to differentiate functions of the form or products and quotients of functions, where taking the natural logarithm of both sides simplifies the differentiation process.

### Application of Derivatives

The derivative is used in various applications such as finding the slope of a curve at a point, determining the rate of change of quantities, and solving problems related to maxima and minima of functions, which is crucial in optimization problems.

The first derivative test and the second derivative test are common methods used to identify local maxima and minima of a function.

These topics build on the foundational concepts of differentiation and are essential for understanding more advanced calculus concepts and solving real-world problems.
