![]() Note that we first use linearity of the derivative to pull the 10 out in front. When I say low de high I mean the derivative of the high function so low de high minus high de low over the square of what's below I'll say that in future lessons just to remind you what the quotient rule is.\] ![]() If you use the power rule plus the product rule, you often must find a common denominator to simplify the result. It's low de high minus high de low over the square of what's below. There are two reasons why the quotient rule can be superior to the power rule plus product rule in differentiating a quotient: It preserves common denominators when simplifying the result. And believe it or not this came from a student I was never taught this a student told me this, so when you're taking a derivative of a function that's a quotient to other functions let's call this one the low function and this one the high function. Now I'm going to put a big box around it, it's an important rule and I also want to give you guys a way of remembering this rule. In the list of problems which follows, most problems are average and a. Note that the numerator of the quotient rule is identical to the ordinary product rule except that subtraction replaces addition. The derivative of f of x over g of x is g of x times f prime of x minus f of x g prime of x over g of x quantity squared. Always start with the bottom function and end with the bottom function squared. Here are useful rules to help you work out the derivatives of many functions (with examples below ). 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. Then the quotient rule tells us that F prime of X is going to be equal to and this is going to look a little bit complicated but once we apply it. There are rules we can follow to find many derivatives. (Low)(D-High) - (High)(D-Low) and then the bottom fraction squared. Oddly enough, its called the Quotient Rule.
