1. product rule of lets say f(x) and g(x)

- tulis f(x)darab g(x) TAMBAH f(x)darab g(x) 

f(x)g(x)+f(x)g(x)

- kemudian prime atau differentiatekan term di SETIAP PENGHUJUNG
f'(x)g(x) + f(x)g'(x)

2. Division rule a.k.a. quotient rule

- tulis f(x) darab g(x) TOLAK f(x) darab g(x)
f(x)g(x) - f(x)g(x)

- kemudian prime atau differentiatekan term di SETIAP PENGHUJUNG
f'(x)g(x) + f(x)g'(x)

- bahagikan dengan denominator kuasa dua
[ f'(x)g(x) + f(x)g'(x) ] / [ g(x) ]^2
