[1/1 Formula]
    Work: Calculate the value of equation arctan(0.2*2.15)+arctan(0.5*2.15)+arctan(2*2.15) .
    Question type: Mathematical calculation
    Solution:
          arctan(0.2*2.15)+arctan(0.5*2.15)+arctan(2*2.15)
        =arctan0.43+arctan(0.5*2.15)+arctan(2*2.15)
        =arctan0.43+arctan1.075+arctan(2*2.15)
        =arctan0.43+arctan1.075+arctan4.3
        =0.406098+arctan1.075+arctan4.3
        =0.406098+0.821527+arctan4.3
        =0.406098+0.821527+1.3423
        =1.227625+1.3423
        =2.569925

    Answer:arctan(0.2*2.15)+arctan(0.5*2.15)+arctan(2*2.15)=2.569925
