[1/1 Formula]
    Work: Calculate the value of equation arccos(12.84/72)-arccos(71.08/72) .
    Question type: Mathematical calculation
    Solution:
          arccos(12.84/72)-arccos(71.08/72)
        =arccos0.178333-arccos(71.08/72)
        =arccos0.178333-arccos0.987222
        =1.391504-arccos0.987222
        =1.391504-0.160033
        =1.231471

    Answer:arccos(12.84/72)-arccos(71.08/72)=1.231471
