Exercise 2.5 Question 8,9 .Find Derivative. Class 12 Math.

To find the derivative of a function, use specific rules derived from the limit definition, such as the power rule for \(x^{n}\), which states the derivative is \(nx^{n-1}\). For more complex functions, use differentiation rules like the product rule, quotient rule, and chain rule, which allow you to find the derivative of combinations of basic functions without repeatedly using the limit definition itself.
