    The mark scheme says 'Out of phase by pi/180 degrees'. I know why the points are out of phase, but why by 'pi/180 degrees'?

    you can see the 2 points are half a way length from each other right ??

    one wavelength is 360 degrees, so half a wavelength is 180 degrees

    360 degrees can also be written as 2 pi, therefore half a wave length ( 180 degrees) is 1 pi

    Haha. I'm an idiot. I think the "/" might have meant "or", not a division symbol.
    Thanks for answering.

    Ive done the paper - I found it pretty tough (managed to get that question ^^ I think). Do you have the question where theres that water pump and it asks you to work out the power of the pump? Don't think ill get it back for a while and wanted to have a second go at it
