Y=sin^2 (x+1) cos x tentukan d^2y / d^x d = diferensial parsil

Y' = u'v – uv'
u = sin^2 (x+1)
u' = d sin^2 (x+1)/ d sin (x+1) * d sin
(x+1)/ d (x+1) * d (x+1)/d (x)
u' = 2sin(x+1) * cos(x+1) * 1
u' = sin2(x+1)
v = cos x
v' = -sin x
y' = (sin2(x+1)cosx) – (-sin^2(x+1)sinx)
y' = sin2(x+1)cosx + sinx sin^2(x+1)
