Does anyone know how to derive a fraction?
I want to be able to differentiate f(x)=[tex]\frac{x(20-x)}{36}[/tex]
Ill show you what I've done but think I've just simplified it.
f(x)=[tex]\frac{x(20-x)}{36}[/tex]
f(x)=[tex]\frac{(20-x-x)}{36}[/tex]
f(x)=[tex]\frac{(10-x)}{18}[/tex]
Is this correct?...although not sure what the rule I've followed is :(
