\(sin{(\alpha+\beta)}=sin\alpha\cdot{cos\beta}+cos\alpha\cdot{sin\beta}\)
\(cos{(\alpha+\beta)}=cos\alpha\cdot{cos\beta}-sin\alpha\cdot{sin\beta}\)
\(sin{(\alpha-\beta)}=sin\alpha\cdot{cos\beta}-cos\alpha\cdot{sin\beta}\)
\(sin{(\alpha+\beta)}=sin\alpha\cdot{cos\beta}-cos\alpha\cdot{sin\beta}\)
\(cos{(\alpha+\beta)}=cos\alpha\cdot{cos\beta}+sin\alpha\cdot{sin\beta}\)
