― Differentiation means to find derivatives of any function. For finding the derivatives we must have good knowledge of all mathematical formulas and basics of trigonometry. Differentiation comes under the category of calculus, which is a part of mathematics. Derivative shows how a function changes as its input changes. Differentiation is fundamental operation in single variable calculus. If we need to explain differentiation more, then it is a method to find the rate at which any dependent output [...].
