Work: Calculate the value of equation 90-arctan6.97+arctan(6.97/2.8)-arctan(6.97/17.36) .
Question type: Mathematical calculation
Solution:
90-arctan6.97+arctan(6.97/2.8)-arctan(6.97/17.36)
=90-arctan6.97+arctan2.489286-arctan(6.97/17.36)
=90-arctan6.97+arctan2.489286-arctan0.401498
=90-1.428297+arctan2.489286-arctan0.401498
=90-1.428297+1.188807-arctan0.401498
=90-1.428297+1.188807-0.381797
=88.571703+1.188807-0.381797
=89.76051-0.381797
=89.378713
Answer:90-arctan6.97+arctan(6.97/2.8)-arctan(6.97/17.36)=89.378713
