    1. Please don't hijack people's threads. Create a new thread for your question.

    2. You know that 2 sin x cos x = sin 2x. So sin x cos x = 0.5 sin 2x. So 1/(sin x cos x) = 1/(0.5 sin 2x) = 2/sin 2x.

    Hijacking?? I already knew the answer, thought the OP wanted questions we found tough, so I shared the tough part.

    Ah, apologies. I thought you were asking for help. You might want to share questions in a more accessible format, such as a link to the paper or the likes.

    No worries, I agree it wasn't the best format to present it in.

    From part a we know that tan2theta=1/2tan40

    If you type 1/2tan40 into the calculator you get 0.4195..
    I personally let 2theta = y just to make it clearer to myself

    Inverse tan(0.4195..) to get value then use the CAST diagram to calculate theta values! Hope that makes sense if not I will post a photo of my solution
