Unformatted text preview: x 2 is a particularly simple denominator, but we will see that a similar calculation is usually possible. Another approach is to remember that d dx 1 g ( x ) =g ± ( x ) g ( x ) 2 , but this requires extra memorization. Using this formula, d dx 10 x 2 = 102 x x 4 . Note that we ﬁrst use linearity of the derivative to pull the 10 out in front....
