Calculus

Calculus is the mathematical study of continuous change. The 2 branches are related to each other by the fundamental theorem of calculus. Both branches make use of the fundamental notions of convergence of infinite series & infinite sequences to a well-defined limit.

Differentiable

Definition of Differentiable Differentiable means:  the function has derivative the derivative f’(x) must exist for every value in the function’s domain Examples The use of differentiable function When a function is differentiable, we can use all the power of calculus when working with it. When a function is differentiable, it is continuous. Differentiable ⇒ Continuous … Continue reading "Differentiable"

Integration by Substitution (Reverse Chain Rule)

Definition Integration by Substitution (also called “The Reverse Chain Rule” or “u-Substitution” ) is a method to find an integral, but only when it can be set up in a special way. It is an important method in mathematics. Integration by substitution is the counterpart to the chain rule for differentiation. When it is possible to perform … Continue reading "Integration by Substitution (Reverse Chain Rule)"
