[1/1 Formula]
    Work: Calculate the value of equation 90+arctan(6.67*1.5)-arctan(44.47*1.5)-arctan(0.5*1.5)-arctan(0.5*1.5) .
    Question type: Mathematical calculation
    Solution:
          90+arctan(6.67*1.5)-arctan(44.47*1.5)-arctan(0.5*1.5)-arctan(0.5*1.5)
        =90+arctan10.005-arctan(44.47*1.5)-arctan(0.5*1.5)-arctan(0.5*1.5)
        =90+arctan10.005-arctan66.705-arctan(0.5*1.5)-arctan(0.5*1.5)
        =90+arctan10.005-arctan66.705-arctan0.75-arctan(0.5*1.5)
        =90+arctan10.005-arctan66.705-arctan0.75-arctan0.75
        =90+1.471177-arctan66.705-arctan0.75-arctan0.75
        =90+1.471177-1.555806-arctan0.75-arctan0.75
        =90+1.471177-1.555806-0.643501-arctan0.75
        =90+1.471177-1.555806-0.643501-0.643501
        =91.471177-1.555806-0.643501-0.643501
        =89.915371-0.643501-0.643501
        =89.27187-0.643501
        =88.628369

    Answer:90+arctan(6.67*1.5)-arctan(44.47*1.5)-arctan(0.5*1.5)-arctan(0.5*1.5)=88.628369
