x^1/2 + y^1/2 = a^1/2
y^1/2 = a^1/2 - x^1/2 ====> kedua ruas dikuadratkan
y = (a^1/2 - x^1/2)²

dy/dx = y'
= 2(a^1/2 - x^1/2) . -1/2 x^-1/2 ==> -1/2 x^-1/2 adl turunan dr (a^1/2 - x^1/2)
= 2 . -1/2 x^-1/2 (a^1/2 - x^1/2)
= -x^-1/2 (a^1/2 - x^1/2)
= - a^1/2 x^-1/2 + x^0
= -a^1/2 x^-1/2

d²x/dx² = y''
= 1/2 a^1/2 x^-3/2
= 1/2 x^-3/2 a^1/2
