Class 11 Physics (India): The derivative of x² at x=3 using the formal definition

Sal finds the limit expression for the derivative of f(x)=x² at the point x=3 and evaluates it.

Class 11 Physics (India)

Let's learn, practice, and master topics of class 11 physics (NCERT) starting with kinematics and then moving to dynamics with Newton's laws of motion, work, energy, and power. Let's then use these as the foundation to learn about centre of mass, rotational motion, gravitation, solids, fluids, thermodynamics, and oscillations and waves.

Using the formal definition of derivative

Learn how we can use their formal definition in order to find the derivatives of specific functions. For example, we find the derivative of f(x)=x² at x=3, or for any x-value.
