Work: Calculate the value of equation 90+arctan(6.67*1.5)-arctan(44.47*1.5)-arctan(0.5*1.5)-arctan(0.5*1.5) .
Question type: Mathematical calculation
Solution:
90+arctan(6.67*1.5)-arctan(44.47*1.5)-arctan(0.5*1.5)-arctan(0.5*1.5)
=90+arctan10.005-arctan(44.47*1.5)-arctan(0.5*1.5)-arctan(0.5*1.5)
=90+arctan10.005-arctan66.705-arctan(0.5*1.5)-arctan(0.5*1.5)
=90+arctan10.005-arctan66.705-arctan0.75-arctan(0.5*1.5)
=90+arctan10.005-arctan66.705-arctan0.75-arctan0.75
=90+1.471177-arctan66.705-arctan0.75-arctan0.75
=90+1.471177-1.555806-arctan0.75-arctan0.75
=90+1.471177-1.555806-0.643501-arctan0.75
=90+1.471177-1.555806-0.643501-0.643501
=91.471177-1.555806-0.643501-0.643501
=89.915371-0.643501-0.643501
=89.27187-0.643501
=88.628369
Answer:90+arctan(6.67*1.5)-arctan(44.47*1.5)-arctan(0.5*1.5)-arctan(0.5*1.5)=88.628369
