Differentiation questions with answers are provided here for students of Class 11 and Class 12. Differentiation is an important topic for 11th and 12th standard students as these concepts are further included in higher studies. The problems prepared here are as per the CBSE board and NCERT curriculum. Practising these questions will help students to solve hard problems and to score more marks in the exam.

The differentiation of a function f(x) is represented as f’(x). If f(x) = y, then f’(x) = dy/dx, which means y is differentiated with respect to x. Before we start solving some questions based on differentiation, let us see the general differentiation formulas used here.

Function f(x) = y Differentiation of function f’(x) = dy/dx
