The derivative is a measure of how a function changes as you move closer to a specific point.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Rules_for_Important_Differentiation_Formulas\"><\/span>Rules for Important Differentiation Formulas<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>There are a few key rules to remember when differentiating important formulas.<\/p>\n<p>The first is that the derivative of a constant is always zero. For instance, the derivative of x is zero, and the derivative of y is zero.<\/p>\n<p>The second rule is that the derivative of a sum is the sum of the derivatives. For instance, the derivative of x + y is the sum of the derivatives of x and y.<\/p>\n<p>The third rule is that the derivative of a product is the product of the derivatives. For instance, the derivative of x*y is the product of the derivatives of x and y.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Rules_for_Compound_Functions\"><\/span>Rules for Compound Functions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A compound function is a function that is composed of two or more functions. The rules for working with compound functions are:<\/p>\n<p>1. The functions in a compound function must be compatible. This means that they must have the same number of inputs and the same number of outputs.<\/p>\n<p>2. The functions in a compound function must be nested. This means that the output of one function must be the input to the next function.<\/p>\n<p>3. The order of the functions in a compound function is important. This means that the output of the first function must be the input to the second function, and so on.<\/p>\n<p>4. The order of the inputs to a compound function is important. This means that the input to the first function must be the input to the second function, and so on.<\/p>\n<p>5. The order of the outputs of a compound function is not important. This means that the output of the last function can be the output of the compound function, or it can be passed on to another function.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Sum_or_Difference\"><\/span>Sum or Difference<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The sum of two numbers is the result of adding the numbers together.
