[1/1 Formula]
    Work: Calculate the value of equation -2*sin37+2*cos37-sin18.5 .
    Question type: Mathematical calculation
    Solution:
          -2*sin37+2*cos37-sin18.5
        =-2*-0.643538+2*cos37-sin18.5
        =-2*-0.643538+2*0.765414-sin18.5
        =-2*-0.643538+2*0.765414--0.342481
        =1.287076+2*0.765414-(-0.342481)
        =1.287076+1.530828-(-0.342481)
        =2.817904-(-0.342481)
        =3.160385

    Answer:-2*sin37+2*cos37-sin18.5=3.160385
