y = u/v
u = 4sinx --> u' = 4cosx
v = 3+5cosx --> v' = -5sinx
y' = (u'v-uv')/v²
y' = (4cosx.(3+5cosx) - 4sinx.-5sinx)/(3+5cosx)²
y' = (12cosx+20cos²x+20sin²x)/(3+5cosx)²
y' = (12cosx+20(cos²x+sin²x))/(3+5cosx)²
y' = (12cosx+20(1))/(3+5cosx)²
y' = (12cosx+20)/(3+5cosx)²
y' = 4(3cosx+5)/(3+5cosx)²

u'(x) = 4 cosx
v(x) = 3+5 cosx
v'(x) = 0-5 sinx = -5 sinx
