    Hello guys,

    I have a small confusion in the attached question. First I converted the sin^2 using formula to cosine. Then I used scaling property which states that x(t) becomes (1/a) X(w/a). Okay for simplicity, w means omega. I currently have x(t)=cos(wt) + ((1/2)-(1/2)cos(2wt)) and I really don't know how would I find X(w) and apply the scaling property over it. Any help would be whole heartedly appreciated.
    I have already solved this thing using Euler's but the point is now I want to solve it using the property. The main thing is I need to use the property and I am confused about it.
    Waiting for your replies.
