In this article, we will show you how to do that step by step. We will also tell you more about differential calculus, Das and Mukherjee, their book, how to use it effectively, what are the pros and cons of downloading it for free, and what are some alternatives to their book. By the end of this article, you will have all the information you need to start learning differential calculus with Das and Mukherjee's book.

## What is Differential Calculus?

Differential calculus is a branch of mathematics that studies the rate of change of quantities. It involves finding the derivative of a function, which is a measure of how fast the function changes with respect to its input variable. For example, if f(x) = x^2 + 3x - 5, then the derivative of f(x) with respect to x is f'(x) = 2x + 3. This means that for every unit increase in x, f(x) increases by 2x + 3 units.

Differential calculus also deals with finding the slope of a curve at a given point, which is equal to the derivative of the function that defines the curve at that point. For example, if y = x^3 - 2x + 1, then the slope of the curve y at x = 2 is y'(2) = 3(2)^2 - 2 = 10. This means that at x = 2, the curve y is rising at an angle of tan^-1(10) degrees.

Differential calculus also helps us find the maximum or minimum values of a function or a curve, which are called extrema. These are the points where the derivative of the function or the curve is zero or undefined. For example, if y = x^4 - 4x^3 + 6x^2 - 4x + 1, then the extrema of y are at x = 0, x = 1, and x = 2. These are the points where y'(x) = 4x^3 - 12x^2 + 12x - 4 = 0 or undefined.

## Why is Differential Calculus Important?

Differential calculus is important because it has many applications in various fields of science, engineering, economics, and other disciplines. Some of the examples are:

Differential calculus helps us model and analyze physical phenomena that involve rates of change, such as motion, acceleration, force, work, energy, power, heat, electricity, magnetism, sound, light, etc.

Differential calculus helps us optimize systems and processes that involve finding the best or optimal solution among many possible alternatives, such as maximizing profit, minimizing cost, maximizing efficiency, minimizing waste, etc.

Differential calculus helps us approximate complex functions and curves with simpler ones, such as polynomials, trigonometric functions, exponential functions, logarithmic functions, etc. This makes it easier to calculate and manipulate them.

Differential calculus helps us understand and interpret graphs and charts that show the relationship between two or more variables, such as supply and demand curves, production functions, marginal utility curves, etc.

Differential calculus helps us solve differential equations, which are equations that relate a function and its derivatives. Differential equations are used to model and describe many natural and artificial phenomena, such as population growth, radioactive decay, chemical reactions, fluid dynamics, etc.
