## Power Rule – Examples and Practice Problems

Derivation exercises that involve the variables or functions raised to a numerical exponent can be solved using the power rule formula. This formula allows us to derive variables such as but not limited to , where is either a positive, negative or rational real...

## Power Rule of Derivatives – Formula, Proof and Examples

The Power Rule is one of the major and most commonly used formulas in Differential Calculus (or Calculus I). It is commonly applied in deriving a single variable, a set of polynomials, or a function with a numerical exponent. The power rule can be proven and...

## Proofs of the Power Rule of Derivatives

The Power Rule is one of the most commonly used derivative rules in Differential Calculus (or Calculus I) to derive a variable raised a numerical exponent. In special cases, if supported by another derivative rule, it is also used to derive a  transcendental...

## Chain Rule – Formula, Proof and Examples

The Chain Rule is one of the most common derivatives applied in Differential Calculus (or Calculus I). It is used in deriving a composition of functions. The chain rule can be proven using the backbone of Calculus, which is the limits.  In this article,...

## Chain Rule – Examples and Practice Problems

Derivation problems that involve the composition of functions can be solved using the chain rule formula. This formula allows us to derive a composition of functions such as but not limited to f(g(x)). Here, we will look at a summary of the chain rule....

## Proof of The Chain Rule

The Chain Rule is one of the major tools used in Differential Calculus (or Calculus I) derivation applications. It is very essential for the derivative of compositions of at least two different types of functions. However, as easy as it seems to just use a standard...
