Work: Calculate the value of equation 90-arctan(0.2*2.19)-arctan(0.0625*2.19)+arctan(4.8*2.19)-arctan(80*2.19) .
Question type: Mathematical calculation
Solution:
90-arctan(0.2*2.19)-arctan(0.0625*2.19)+arctan(4.8*2.19)-arctan(80*2.19)
=90-arctan0.438-arctan(0.0625*2.19)+arctan(4.8*2.19)-arctan(80*2.19)
=90-arctan0.438-arctan0.136875+arctan(4.8*2.19)-arctan(80*2.19)
=90-arctan0.438-arctan0.136875+arctan10.512-arctan(80*2.19)
=90-arctan0.438-arctan0.136875+arctan10.512-arctan175.2
=90-0.41283-arctan0.136875+arctan10.512-arctan175.2
=90-0.41283-0.13603+arctan10.512-arctan175.2
=90-0.41283-0.13603+1.475952-arctan175.2
=90-0.41283-0.13603+1.475952-1.565089
=89.58717-0.13603+1.475952-1.565089
=89.45114+1.475952-1.565089
=90.927092-1.565089
=89.362003
Answer:90-arctan(0.2*2.19)-arctan(0.0625*2.19)+arctan(4.8*2.19)-arctan(80*2.19)=89.362003
