The power rule Say . To find its derivative, take the power, 5, bring it in front of the x, and reduce the power by 1 (in this example, the power becomes a 4). That gives you . Piece o' cake. indd 49 4/8/10 9:57 AM 50 Calculus Essentials For Dummies In Chapter 4, I differentiate with the difference quotient. It takes eight lines of math to do it. Instead of all that, just use the power rule: Bring the 2 in front, reduce the power by 1, which leaves you with a power of 1 that you can drop (because a power of 1 does nothing).

The power rule works for positive, negative, and fraction powers. Make sure you remember how to do the last function. It’s the simplest function, yet the easiest problem to miss. You can just memorize that the derivative of x is 1. Or do it like this: Rewrite as and then apply the power rule: Bring the 1 in front and reduce the power by 1 to zero, giving you . Because equals 1, you’ve got . You can differentiate radical functions by rewriting them as power functions and then using the power rule.

You can differentiate radical functions by rewriting them as power functions and then using the power rule. For example, , rewrite it as and use the power rule. if You can also use the power rule to differentiate functions like . Rewrite this as and use the power rule. The constant multiple rule What if the function you’re differentiating begins with a coefficient? Makes no difference. A coefficient has no effect on differentiation. indd 50 4/8/10 9:57 AM 51 Chapter 5: Differentiation Rules the appropriate rule.
