Penyelesaian integral tersebut menggunakan metode integral substitusi sebagai berikut. Misal: Dengan demikian,

Penyelesaian integral tersebut menggunakan metode integral substitusi sebagai berikut.

integral 6 x square root of 6 minus x squared end root space text dx end text

Misal: $u equals 6 minus x squared space rightwards arrow space fraction numerator d u over denominator d x end fraction equals negative 2 x space text atau end text space d x equals fraction numerator d u over denominator negative 2 x end fraction$

$table attributes columnalign right center left columnspacing 0px end attributes row cell integral 6 x square root of 6 minus x squared end root space d x end cell equals cell integral 6 x open parentheses u close parentheses to the power of 1 half end exponent times fraction numerator d u over denominator negative 2 x end fraction end cell row blank equals cell integral negative 3 open parentheses u close parentheses to the power of 1 half end exponent space d u end cell row blank equals cell negative 3 times 2 over 3 open parentheses u close parentheses to the power of 3 over 2 end exponent plus c end cell row blank equals cell negative 2 u square root of u plus c end cell row blank equals cell negative 2 open parentheses 6 minus x squared close parentheses square root of 6 minus x squared end root plus c end cell end table$

Dengan demikian,
