In this section, we develop rules for finding derivatives that allow us to bypass this process. We begin with the basics. The Basic Rules. The functions f (x) = c f (x) = c and g (x) = x n g (x) = x n where n n is a positive integer are the building blocks from which all polynomials and rational functions are constructed. To find derivatives of ...
The Derivative tells us the slope of a function at any point. There are rules we can follow to find many derivatives. For example: The slope of a constant value (like 3) is always 0. The slope of a line like 2x is 2, or 3x is 3 etc. and so on.
We begin by applying the rule for differentiating the sum of two functions, followed by the rules for differentiating constant multiples of functions and the rule for differentiating powers. To better understand the sequence in which the differentiation rules are applied, we use Leibniz notation throughout the solution:
Another common interpretation is that the derivative gives us the slope of the line tangent to the function's graph at that point. Learn how we define the derivative using limits. Learn about a bunch of very useful rules (like the power, product, and quotient rules) that help us find derivatives quickly.
In this section (and in some sections to follow) we will learn some of what mathematicians have already discovered about the derivatives of certain functions and how derivatives interact with arithmetic operations.
Differentiation rules are formulae that allow us to find the derivatives of functions quickly. Taking derivatives of functions follows several basic rules: multiplication by a constant: ...
Differentiation Rules. Learning Objectives. State the constant, constant multiple, and power rules. Apply the sum and difference rules to combine derivatives. Use the product rule for finding the derivative of a product of functions. Use the quotient rule for finding the derivative of a quotient of functions.
The sum and difference rule for derivatives states that if f (x) and g (x) are both differentiable functions, then: Derivative Sum Difference — Formula. Constant Multiple Rule. The constant multiple rule states that if c is a constant and f (x) is a differentiable function, then: Constant Multiple Rule. Product Rule.
