Work: Calculate the value of equation 90+arctan(4.8/2.5)-arctan(4.8/5)-arctan(2.4)-arctan(4.8/12.5) .
Question type: Mathematical calculation
Solution:
90+arctan(4.8/2.5)-arctan(4.8/5)-arctan(2.4)-arctan(4.8/12.5)
=90+arctan1.92-arctan(4.8/5)-arctan(2.4)-arctan(4.8/12.5)
=90+arctan1.92-arctan0.96-arctan(2.4)-arctan(4.8/12.5)
=90+arctan1.92-arctan0.96-arctan2.4-arctan(4.8/12.5)
=90+arctan1.92-arctan0.96-arctan2.4-arctan0.384
=90+1.090621-arctan0.96-arctan2.4-arctan0.384
=90+1.090621-0.764993-arctan2.4-arctan0.384
=90+1.090621-0.764993-1.176005-arctan0.384
=90+1.090621-0.764993-1.176005-0.366638
=91.090621-0.764993-1.176005-0.366638
=90.325628-1.176005-0.366638
=89.149623-0.366638
=88.782985
Answer:90+arctan(4.8/2.5)-arctan(4.8/5)-arctan(2.4)-arctan(4.8/12.5)=88.782985
