    Please rephrase your entire question using proper and syntax-checked sentences and expressions.

    No, that is not an equation. An equation contains the equal sign.

    Is what you mean:

    1. (cos(30)-A) + sin(60 + A)
    2. cos(30-A) + sin(60 + A)
    3. cos(30-A + sin(60 + A))

    In the cases of 1 and 3, there are no better ways to reduce the number of terms. In the case of 2, I already gave the result.
