  1. sin is a mathematical operator such as √ , ÷ etc.

    by itself it is meaningless, it must have an operand behind it, i.e. sinx or sinØ
    (that is like saying: evaluate 1/√ - √ )

    1/sinØ - sinØ
    = (1 - sin^2 Ø)/(sinØ
    = cos^2 Ø/sinØ

    which is in terms of sines and cosines as requested
    (I would have simplified it to
    cotØcosØ )
