Ingat!

f left parenthesis x right parenthesis equals a x to the power of n f apostrophe left parenthesis x right parenthesis equals n times a x to the power of n minus 1 end exponent  f left parenthesis x right parenthesis equals u over v f apostrophe left parenthesis x right parenthesis equals fraction numerator u apostrophe v minus u v apostrophe over denominator v squared end fraction

Sehingga,

table attributes columnalign right center left columnspacing 0px end attributes row cell f left parenthesis x right parenthesis end cell equals cell fraction numerator 3 t squared plus 4 t cubed over denominator t cubed end fraction end cell row blank equals cell fraction numerator t squared left parenthesis 3 plus 4 t right parenthesis over denominator t cubed end fraction end cell row blank equals cell fraction numerator 4 t plus 3 over denominator t end fraction end cell end table

Misal:

table attributes columnalign right center left columnspacing 0px end attributes row u equals cell 4 t plus 3 end cell row cell u apostrophe end cell equals 4 row blank blank blank row v equals t row cell v apostrophe end cell equals 1 end table

Maka, 

table attributes columnalign right center left columnspacing 0px end attributes row cell f apostrophe left parenthesis x right parenthesis end cell equals cell fraction numerator u apostrophe v minus u v apostrophe over denominator v squared end fraction end cell row blank equals cell fraction numerator 4 left parenthesis t right parenthesis minus left parenthesis 4 t plus 3 right parenthesis left parenthesis 1 right parenthesis over denominator t squared end fraction end cell row blank equals cell fraction numerator 4 t minus 4 t plus 3 over denominator t squared end fraction end cell row blank equals cell 3 over t squared end cell end table

Dengan demikian, turunan dari undefined adalah t squared.
