    Work: Calculate the value of equation 90-arctan4-arctan0.56-arctan0.28-arctan75.6 .
    Question type: Mathematical calculation
    Solution:
          90-arctan4-arctan0.56-arctan0.28-arctan75.6
        =90-1.325818-arctan0.56-arctan0.28-arctan75.6
        =90-1.325818-0.510488-arctan0.28-arctan75.6
        =90-1.325818-0.510488-0.273009-arctan75.6
        =90-1.325818-0.510488-0.273009-1.55757
        =88.674182-0.510488-0.273009-1.55757
        =88.163694-0.273009-1.55757
        =87.890685-1.55757
        =86.333115

    Answer:90-arctan4-arctan0.56-arctan0.28-arctan75.6=86.333115
