[1/1 Formula]
    Work: Calculate the value of equation arctan(2.3/0.23)+arctan(2.3/0.0132)+arctan(2.3*0.25)+arctan(2.3*0.0625) .
    Question type: Mathematical calculation
    Solution:
          arctan(2.3/0.23)+arctan(2.3/0.0132)+arctan(2.3*0.25)+arctan(2.3*0.0625)
        =arctan10+arctan(2.3/0.0132)+arctan(2.3*0.25)+arctan(2.3*0.0625)
        =arctan10+arctan174.242424+arctan(2.3*0.25)+arctan(2.3*0.0625)
        =arctan10+arctan174.242424+arctan0.575+arctan(2.3*0.0625)
        =arctan10+arctan174.242424+arctan0.575+arctan0.14375
        =1.471128+arctan174.242424+arctan0.575+arctan0.14375
        =1.471128+1.565057+arctan0.575+arctan0.14375
        =1.471128+1.565057+0.521834+arctan0.14375
        =1.471128+1.565057+0.521834+0.142772
        =3.036185+0.521834+0.142772
        =3.558019+0.142772
        =3.700791
    Answer:arctan(2.3/0.23)+arctan(2.3/0.0132)+arctan(2.3*0.25)+arctan(2.3*0.0625)=3.700791
