Work: Calculate the value of equation 90+arctan(12.6)-arctan(12.6/2)-arctan(12.6/5)-arctan(12.6/10) .
Question type: Mathematical calculation
Solution:
90+arctan(12.6)-arctan(12.6/2)-arctan(12.6/5)-arctan(12.6/10)
=90+arctan12.6-arctan(12.6/2)-arctan(12.6/5)-arctan(12.6/10)
=90+arctan12.6-arctan6.3-arctan(12.6/5)-arctan(12.6/10)
=90+arctan12.6-arctan6.3-arctan2.52-arctan(12.6/10)
=90+arctan12.6-arctan6.3-arctan2.52-arctan1.26
=90+1.491597-arctan6.3-arctan2.52-arctan1.26
=90+1.491597-1.413379-arctan2.52-arctan1.26
=90+1.491597-1.413379-1.19303-arctan1.26
=90+1.491597-1.413379-1.19303-0.899939
=91.491597-1.413379-1.19303-0.899939
=90.078218-1.19303-0.899939
=88.885188-0.899939
=87.985249
Answer:90+arctan(12.6)-arctan(12.6/2)-arctan(12.6/5)-arctan(12.6/10)=87.985249
