In the previuos topic, we found out the slope of the tangent which was the derivative of the function, we had actually found something called the first principle of calculus!
So, the thing in the red box there is the first principle which we will use to find the derivatives of a function. This process, of finding derivatives(notation:dy/dx) or the differential coefficients of functions may be called Differentiation & we are said to differentiate functions while finding the derivatives.
<!—So, lets start Differentiating Functions Using The First Principle—!>
