    Work: Calculate the value of equation tan(arccos0.63)-tan(arccos0.92) .
    Question type: Mathematical calculation
    Solution:
          tan(arccos0.63)-tan(arccos0.92)
        =tan0.889243-tan(arccos0.92)
        =tan0.889243-tan0.402716
        =1.23269-tan0.402716
        =1.23269-0.425998
        =0.806692
    Answer:tan(arccos0.63)-tan(arccos0.92)=0.806692
