• 1. TURUNAN PARSIAL
Persamaan keadaan gas : PV = RT PV – RT = 0
f (P,V,T) = 0 mempunyai 2 varibel bebas
dan 1 variabel tak bebas
P = P (V,T)
V = V (P,T)
T = T (P,T)
Kita ambil : f (x,y,z) = 0
x = x (y,z)
y = y (x,z)
z = z (x,y)
Contoh :
• 2. TURUNAN PARSIAL
variabel bebas : y, z
misalkan : dz ≠ 0 dan dy = 0
maka :
atau
misal : dz = 0 dan dy ≠ 0
maka :
