Chapter 2 of Differentiation in Mathematics for FSC Part 2 consists of 10 exercises that provide students with a comprehensive understanding of derivatives within calculus.

**Differentiation** is a fundamental concept utilized in calculus to determine the rate of change of a function. It involves calculating derivatives, which signify how one quantity changes concerning another. Essentially, differentiation allows us to analyze how functions behave, their value transitions, and their curvature or slope at specific points.

A concise overview of the entire chapter is as follows:

**Exercises 2.1 and 2.2**: These exercises focus on discovering the derivatives of any function by employing the definition of derivatives.

**Exercise 2.3: **This exercise guides us on how to determine the derivatives of functions using basic rules, such as the Power Rule, Sum/difference Rule, product, and Quotient rule. These fundamental rules assist in simplifying the process of finding derivatives.

**Ex 2.4 **delves into several essential topics within differentiation. It covers the Chain Rule, exploring how to calculate derivatives when functions are intertwined. Additionally, this exercise discusses derivatives of inverse functions, elucidating the differentiation process for functions in the form of parametric equations, and tackling implicit relations.

**Moving on to Ex 2.5**, it enlightens us on the derivatives of trigonometric functions and their inverse counterparts. These exercises aid in comprehending the differentiation principles applied to these specific types of functions.

**Exercises 2.6 and 2.7** focus on the derivatives of exponential and logarithmic functions, presenting methods to calculate their derivatives. Logarithmic differentiation, hyperbolic functions, and their inverses are also investigated within these exercises.

**Exercise 2.8 **explains how to expand functions in a series, like the MacLaurin and Taylor Series. This helps you understand function expansions better.

**Exercises 2.9 and 2.10** provide a geometric interpretation of derivatives, illustrating how derivatives are related to the graph of a function. They also talk about how to find increasing and decreasing functions, relative extrema, critical values, critical points, and how to use derivatives through examples.
