Let `f(theta)=sin theta(sin theta +sin 3 theta). " Then " f(theta)`

Let f(theta)=sin theta(sin theta+sin3 theta)* then

Let f(theta) =sin theta(sin theta + sin3theta) then f(theta) :

Let f(theta)=sin theta(sin theta+sin3 theta)* Then f(theta) is (a) >=0 only when theta>=0(b) =0 for all real theta(d)<=0 only when theta<=0

Let f(theta)=sin theta(sin theta+sin3 theta), then f(theta)(A)>=0 only when theta>=0(B)>=0 for all real theta (C) >=0 for all real theta(D)<=0 only when theta<=0

Let f(theta)=sin theta(sin theta+ sin 30) then f(theta)

Let f(theta)=sintheta(sintheta+sin3theta).Then, f(theta)

Let f(theta)=sintheta(sintheta+sin3theta). then f(theta)

Let f(theta)=sintheta(sintheta+sin3theta) . then f(theta) is
