L {cos (a t + b)} = \frac{s \cdot cos ( b ) - a \cdot sin ( b )}{s ^{2} + a ^{2}}

L {cos (t - \frac{2 π}{3})} = \frac{s cos ( - \frac{2 π}{3} ) - 1 \cdot sin ( - \frac{2 π}{3} )}{s ^{2} + 1 ^{2}}

= \frac{s cos ( - \frac{2 π}{3} ) - 1 \cdot sin ( - \frac{2 π}{3} )}{s ^{2} + 1 ^{2}}

= \frac{- s + 3}{2 ( s ^{2} + 1 )}
