Unformatted text preview: d dx ( f ( x ) g ( x ) ) = g ( x ) f ( x ) f ( x ) g ( x ) [ g ( x )] 2 = lowdhighhighdlow lowsquared the second expression that I typed is a “cute” way to memorize the quotient rule – it seems to stick Again let’s work and example that we can divide out first to avoid the new rule and then use the new rule to verify it is correct. Example j ( x ) = x 4 3 x 2 x a) First, divide j(x) and then differentiate b) Second, use the quotient rule and simplify until we see the methods result in the same function. Further examples:...
