Question

H(x)=(x+π/2)sinx , maka h'(x) adalah? pake caranya yaaa

Answer 1

H'(x) = Cos x
karena semua konstanta kalo sdh aksen itu sama dgn nol

Answer 2

H(x) = (x +π/2) sin x
h(x)= u(x). v(x)
u(x) = x+ π2 --> u' = 1
v(x) = sin x --> v' = - cos x

h' (x)= u' v + u v'
h' (x) = 1 (sin x) + (x+π/2)(-cos x)
h' (x)  =sin x - (x+ π/2).cos x
