Differential Calculus

Welcome to Differential Calculus!

In this lesson, you'll learn the words "derivative" and "differential". They are mostly the same - we will learn the difference in Integral Calculus.

Although they may seem intimidating, the words "differential" and "derivative" just mean "the slope".

For example, if we have a function

f(x)=7x4,f(x) = 7x -4,

then we say the derivative of the function is the slope, which is 77 in this case.

Another way to write this is

df(x)dx=7.\frac{d f(x)}{dx} = 7.
