Work: Calculate the value of equation 90-arctan(10*sqrt(6)/3)-arctan(10*sqrt(6)/6)+arctan(10*sqrt(6)/9) .
Question type: Mathematical calculation
Solution:
90-arctan(10*sqrt(6)/3)-arctan(10*sqrt(6)/6)+arctan(10*sqrt(6)/9)
=90-arctan(10*sqrt6/3)-arctan(10*sqrt(6)/6)+arctan(10*sqrt(6)/9)
=90-arctan8.164967-arctan(10*sqrt(6)/6)+arctan(10*sqrt(6)/9)
=90-arctan8.164967-arctan(10*sqrt6/6)+arctan(10*sqrt(6)/9)
=90-arctan8.164967-arctan4.082483+arctan(10*sqrt(6)/9)
=90-arctan8.164967-arctan4.082483+arctan(10*sqrt6/9)
=90-arctan8.164967-arctan4.082483+arctan2.721656
=90-1.448929-arctan4.082483+arctan2.721656
=90-1.448929-1.330577+arctan2.721656
=90-1.448929-1.330577+1.218685
=88.551071-1.330577+1.218685
=87.220494+1.218685
=88.439179
Answer:90-arctan(10*sqrt(6)/3)-arctan(10*sqrt(6)/6)+arctan(10*sqrt(6)/9)=88.439179
