Hai teman teman mohon bantuannta ya nomor 34

Π/3 = 180°/3
= 60°

f(x) = sinx/(1+cosx)

u = sinx
u' = cosx
v = 1 + cosx
v' = -sinx

f'(x) = (u'v – uv')/v²
= (cosx(1 + cosx) – sinx(-sinx))/(1 + cosx)²
= (cosx + cos²x + sin²x)/(1 + cosx)²
= (1 + cosx)/(1 + cosx)²
= 1/(1 + cosx)

f'(60°) = 1/(1 + cos(60°))
= 1/(1 + 1/2)
= 1/((2 + 1)/2)
= 1/(3/2)
= 2/3
