  • misal : u = x²       dan    v = x² + 1
               u' = 2x                v' = 2x

     [tex]f (x) = \frac{ X^{2} }{ X^{2} + 1} [/tex]

     [tex]f (x) = \frac{u}{v} [/tex]

    [tex]f' (x) = \frac{u' . v - u . v'}{ v^{2} } [/tex]
         
            [tex]= \frac{2X ( X^{2} + 1) - X^{2} (2X)}{ ( X^{2} + 1)^{2} } [/tex]
            
            [tex]= \frac{2 X^{3} + 2X - 2 X^{2} }{ (X^{2} + 1) ^{2} } [/tex]
           
            [tex]= \frac{2X}{ (X^{2} + 1)^{2} } ..... jawaban : B[/tex]
