Rational_functions_differentiation_intro_
Learn how the power rule can be used to differentiate some basic rational functions.
If you ever tried to find derivatives using their formal definition, you probably know how tedious that may be. Fortunately, we have ways for finding derivatives much quicker, using differentiation rules! Make your first steps in this fascinating world by working with the more basic rules. For example, the derivative of [f(x)+g(x)] is f'(x)+g'(x), and the derivative of k⋅f(x) is k⋅f'(x).
The derivative of eˣ is eˣ. That's pretty amazing. The derivative of ln(x) is 1/x, which is just as surprising.
Review your understanding of basic differentiation rules and your knowledge of the derivatives of common functions with some challenge problems.
The power rule says that the derivative of xⁿ is n⋅xⁿ⁻¹. It allows us to quickly find the derivative of any polynomial, and it doesn't even stop there! Make introduction with this simple but powerful rule.
The derivative of sin(x) is cos(x) and the derivative of cos(x) is -sin(x). How convenient! Practice differentiating functions that include sine and cosine.
