[1/1 Formula]
    Work: Calculate the value of equation 0.5*(e^(1.6977)+e^(-1.6977))*sin(1.6977)-0.5*(e^(1.6977)-e^(-1.6977))*cos(1.6977) .
    Question type: Mathematical calculation
    Solution:
          0.5*(e^(1.6977)+e^(-1.6977))*sin(1.6977)-0.5*(e^(1.6977)-e^(-1.6977))*cos(1.6977)
        =0.5*(e^1.6977+e^(-1.6977))*sin(1.6977)-0.5*(e^(1.6977)-e^(-1.6977))*cos(1.6977)
        =0.5*(e^1.6977+e^(-1.6977))*sin(1.6977)-0.5*(e^(1.6977)-e^(-1.6977))*cos(1.6977)
        =0.5*5.644477*sin(1.6977)-0.5*(e^(1.6977)-e^(-1.6977))*cos(1.6977)
        =0.5*5.644477*sin1.6977-0.5*(e^(1.6977)-e^(-1.6977))*cos(1.6977)
        =0.5*5.644477*sin1.6977-0.5*(e^1.6977-e^(-1.6977))*cos(1.6977)
        =0.5*5.644477*sin1.6977-0.5*(e^1.6977-e^(-1.6977))*cos(1.6977)
        =0.5*5.644477*sin1.6977-0.5*5.278268*cos(1.6977)
        =0.5*5.644477*sin1.6977-0.5*5.278268*cos1.6977
        =0.5*5.644477*0.991959-0.5*5.278268*cos1.6977
        =0.5*5.644477*0.991959-0.5*5.278268*-0.126563
        =2.822239*0.991959-0.5*5.278268*(-0.126563)
        =2.799545-0.5*5.278268*(-0.126563)
        =2.799545-2.639134*(-0.126563)
        =2.799545-(-0.334017)
        =3.133562

    Answer:0.5*(e^(1.6977)+e^(-1.6977))*sin(1.6977)-0.5*(e^(1.6977)-e^(-1.6977))*cos(1.6977)=3.133562
