Derivatives from first principles
WebJan 25, 2024 · First Principle of Differentiation: Derivative as a Rate Measurer, Geometrical Interpretation of Derivative at a Point A derivative is the first of the two main tools of calculus (the second being the integral). It is the instantaneous rate of change of a function at a point in its domain. WebThe derivative of \sqrt{x} can also be found using first principles. Plugging \sqrt{x} into the definition of the derivative, we multiply the numerator and denominator by the conjugate of the numerator, \sqrt{x+h}+\sqrt{x}. Simplifying and taking the limit, the derivative is found to be \frac{1}{2\sqrt{x}}.
