Differential Calculus – The First Principle


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!
first principle
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.
