[1/1 Formula]
    Work: Calculate the value of equation sqrt(2.4^2+3.2^2)*(cos(0.5*(53.13-44)))/(cos(0.5*(53.13+44))) .
    Question type: Mathematical calculation
    Solution:
          sqrt(2.4^2+3.2^2)*(cos(0.5*(53.13-44)))/(cos(0.5*(53.13+44)))
        =sqrt16*(cos(0.5*(53.13-44)))/(cos(0.5*(53.13+44)))
        =sqrt16*(cos(0.5*9.13))/(cos(0.5*(53.13+44)))
        =sqrt16*(cos4.565)/(cos(0.5*(53.13+44)))
        =sqrt16*(-0.146856)/(cos(0.5*(53.13+44)))
        =sqrt16*(-0.146856)/(cos(0.5*97.13))
        =sqrt16*(-0.146856)/(cos48.565)
        =sqrt16*(-0.146856)/(-0.129323)
        =4*-0.146856/-0.129323
        =-0.587424/(-0.129323)
        =4.542301

    Answer:sqrt(2.4^2+3.2^2)*(cos(0.5*(53.13-44)))/(cos(0.5*(53.13+44)))=4.542301
