## FAQs on Differentiation Rules Video Lecture - Physics for JEE Main & Advanced

 1. What are the basic rules of differentiation?
Ans. The basic rules of differentiation include the power rule, product rule, quotient rule, and chain rule. The power rule states that if a function is raised to a power, the derivative is found by multiplying the power by the original function raised to the power minus one. The product rule is used when differentiating the product of two functions, and it states that the derivative is found by multiplying the derivative of the first function by the second function, plus the derivative of the second function multiplied by the first function. The quotient rule is similar to the product rule, but it is used when differentiating the quotient of two functions. The chain rule is used when differentiating composite functions, and it states that the derivative is found by multiplying the derivative of the outer function with the derivative of the inner function.
 2. How do I differentiate a function using the power rule?
Ans. To differentiate a function using the power rule, you need to identify the power to which the function is raised. Let's say you have a function f(x) = x^n, where n is a constant. The power rule states that the derivative of this function is given by f'(x) = n * x^(n-1). Therefore, you simply multiply the power by the original function raised to the power minus one to find the derivative.
 3. Can you explain the product rule for differentiation?
Ans. The product rule is used when differentiating the product of two functions. Let's say you have two functions, f(x) and g(x), and you want to find the derivative of their product, h(x) = f(x) * g(x). The product rule states that the derivative of the product is given by h'(x) = f'(x) * g(x) + f(x) * g'(x). In other words, you differentiate the first function and multiply it by the second function, then add that to the product of the first function and the derivative of the second function.
 4. How do I differentiate a quotient of two functions using the quotient rule?
Ans. The quotient rule is used when differentiating the quotient of two functions. Let's say you have two functions, f(x) and g(x), and you want to find the derivative of their quotient, h(x) = f(x) / g(x). The quotient rule states that the derivative of the quotient is given by h'(x) = (f'(x) * g(x) - f(x) * g'(x)) / (g(x))^2. In other words, you differentiate the numerator and multiply it by the denominator, then subtract that from the product of the numerator and the derivative of the denominator, and finally divide the whole expression by the square of the denominator.
 5. When should I use the chain rule for differentiation?
Ans. The chain rule is used when differentiating composite functions, which are functions within functions. For example, if you have a function f(x) = g(h(x)), where g(x) and h(x) are both functions, then you would need to use the chain rule to find the derivative of f(x). The chain rule states that if you have a composite function, the derivative is found by multiplying the derivative of the outer function with the derivative of the inner function. In other words, you differentiate the outer function with respect to the inner function, and then multiply it by the derivative of the inner function with respect to the input variable.
