Work: Calculate the value of equation 90+arctan(4.2*2.5)-arctan(0.1*2.5)-arctan(0.2*2.5)-arctan(41*2.5) .
Question type: Mathematical calculation
Solution:
90+arctan(4.2*2.5)-arctan(0.1*2.5)-arctan(0.2*2.5)-arctan(41*2.5)
=90+arctan10.5-arctan(0.1*2.5)-arctan(0.2*2.5)-arctan(41*2.5)
=90+arctan10.5-arctan0.25-arctan(0.2*2.5)-arctan(41*2.5)
=90+arctan10.5-arctan0.25-arctan0.5-arctan(41*2.5)
=90+arctan10.5-arctan0.25-arctan0.5-arctan102.5
=90+1.475845-arctan0.25-arctan0.5-arctan102.5
=90+1.475845-0.244979-arctan0.5-arctan102.5
=90+1.475845-0.244979-0.463648-arctan102.5
=90+1.475845-0.244979-0.463648-1.561041
=91.475845-0.244979-0.463648-1.561041
=91.230866-0.463648-1.561041
=90.767218-1.561041
=89.206177
Answer:90+arctan(4.2*2.5)-arctan(0.1*2.5)-arctan(0.2*2.5)-arctan(41*2.5)=89.206177
