Work: Calculate the value of equation 90+arctan(15.15*0.57)-arctan(0.57)-arctan(0.25*0.57)-arctan(114.78*0.57) .
Question type: Mathematical calculation
Solution:
90+arctan(15.15*0.57)-arctan(0.57)-arctan(0.25*0.57)-arctan(114.78*0.57)
=90+arctan8.6355-arctan(0.57)-arctan(0.25*0.57)-arctan(114.78*0.57)
=90+arctan8.6355-arctan0.57-arctan(0.25*0.57)-arctan(114.78*0.57)
=90+arctan8.6355-arctan0.57-arctan0.1425-arctan(114.78*0.57)
=90+arctan8.6355-arctan0.57-arctan0.1425-arctan65.4246
=90+1.455509-arctan0.57-arctan0.1425-arctan65.4246
=90+1.455509-0.518069-arctan0.1425-arctan65.4246
=90+1.455509-0.518069-0.141547-arctan65.4246
=90+1.455509-0.518069-0.141547-1.555513
=91.455509-0.518069-0.141547-1.555513
=90.93744-0.141547-1.555513
=90.795893-1.555513
=89.24038
Answer:90+arctan(15.15*0.57)-arctan(0.57)-arctan(0.25*0.57)-arctan(114.78*0.57)=89.24038
