In calculus, the sum rule in differentiation is a method of finding the derivative of a function that is the sum of two other functions for which derivatives exist. This is a part of the linearity of differentiation.
Derivative of sum of two functions is …… of the derivati...
**Explanation:**
To find the derivative of the sum of two functions, we need to apply the derivative operator to each function separately and then add the two resulting derivatives together.
Let's consider two differentiable functions, f(x) and g(x), and their sum h(x) = f(x) + g(x).
To find the derivative of h(x), we apply the derivative operator to each term separately:
h'(x) = (f(x) + g(x))'
By applying the derivative operator to each term, we get:
h'(x) = f'(x) + g'(x)
So, the derivative of the sum of two functions is the sum of the derivatives of the individual functions.
This can be represented mathematically as:
(d/dx) (f(x) + g(x)) = (d/dx) f(x) + (d/dx) g(x)
Therefore, the correct answer is option **b) Sum**, as the derivative of the sum of two functions is the sum of the derivatives of the individual functions.
