$\displaystyle 2\,\sin(\frac{1}{3}\,\pi +A)$ Reply if you need more explanations.
the equations is cos(30(degrees)-A + sin(60(degrees) + A) is one of the froms of this equation $\displaystyle sinx$

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. $\displaystyle (cos(30)-A) + sin(60 + A)$ 2. $\displaystyle cos(30-A) + sin(60 + A)$ 3. $\displaystyle cos(30-A + sin(60 + A))$

In the case of 2, I already gave the result.
