Derivative

# Idea

Derivative can be written as a quotient of two differentials:

(1)
\begin{align} f'(x)=\frac{df(x)}{dx} \end{align}

where differentials can be taken with respect to any variable.

## Where it can be used?

• Slope of tangent line
• velocity, acceleration, etc. computation
• Differential equations
