Work: Calculate the value of equation 80-90-arctan(0.5*1.28)-arctan(0.125*1.28) .
Question type: Mathematical calculation
Solution:
80-90-arctan(0.5*1.28)-arctan(0.125*1.28)
=80-90-arctan0.64-arctan(0.125*1.28)
=80-90-arctan0.64-arctan0.16
=80-90-0.569313-arctan0.16
=80-90-0.569313-0.158655
=-10-0.569313-0.158655
=-10.569313-0.158655
=-10.727968
Answer:80-90-arctan(0.5*1.28)-arctan(0.125*1.28)=-10.727968
