Topics Covered in Exercise 5.2 Class 12 Mathematics Questions
Exercise 5.2 class 12 maths chapter 5 explains differentiability and derivatives of composite functions in NCERT solutions provided by eSaral.
1. 
Differentiability 
Derivatives of composite functions 

Differentiability
Let say f is a real function and c is a point in its domain. The derivative of f at c is defined by
$\lim _{h \rightarrow 0} \frac{f(c+h)f(c)}{h}$
provided this limit exists. Derivative of f at c is denoted by f ′(c) or ( ( ))  c d f x dx . The function defined by
$f^{\prime}(x)=\lim _{h \rightarrow 0} \frac{f(x+h)f(x)}{h}$
The process of finding derivatives of a function is called differentiation.
The following rules were established as a part of algebra of derivatives:
(1) (u ± v)′ = u′ ± v′
(2) (uv)′ = u′v + uv′ (Leibnitz or product rule)
(3) $\left(\frac{u}{v}\right)^{\prime}=\frac{u^{\prime} vu v^{\prime}}{v^2}$ , wherever v ≠ 0 (Quotient rule).
Theorem 3: If a function f is differentiable at a point c, then it is also continuous at that point.

Derivatives of composite functions
Origin of The composite function's derivative is known as the composite function. When a variable is also a function of the variable, the function is called a composite function. It is simple to find the derivative of these functions, using the derivative of the composite function formula.
Theorem 4: (Chain Rule) Let f be a real valued function which is a composite of two functions u and v ; i.e., f = v o u. Suppose t = u(x) and if both dtdx and dvdt exist, we have
$\frac{d f}{d x}=\frac{d v}{d t} \cdot \frac{d t}{d x}$

Frequently Asked Questions
The derivative of a composite function is known as a derivative of that function. The chain rule is used to find the derivative of the composite function..
Chain rule is a rule to differentiate composites of functions. If f = v o u, t = u (x) and if both dt/dx and dv/dt exist then $\frac{d f}{d x}=\frac{d v}{d t} \cdot \frac{d t}{d x}$
