化简-a(ae^{iWT}+Le^{iOT}+c)^3

解答

化简

- a (a e^{iW T} + L e^{i OT} + c)^{3}

- a (a (cos (W T) + i sin (W T)) + L (cos (TO) + i sin (TO)) + c)^{3}

求解步骤

- a (a e^{iW T} + L e^{i OT} + c)^{3}

(a e^{iW T} + L e^{i OT} + c)^{3} = (a (cos (W T) + i sin (W T)) + L (cos (TO) + i sin (TO)) + c)^{3}

= - a (a (cos (W T) + i sin (W T)) + L (cos (TO) + i sin (TO)) + c)^{3}
