Work: Calculate the value of equation 90-arctan(9.41×0.425)-arctan0.425-arctan(0.5×0.425)-arctan(110.68×0.425) .
Question type: Mathematical calculation
Solution:
90-arctan(9.41×0.425)-arctan0.425-arctan(0.5×0.425)-arctan(110.68×0.425)
=90-arctan3.99925-arctan0.425-arctan(0.5×0.425)-arctan(110.68×0.425)
=90-arctan3.99925-arctan0.425-arctan0.2125-arctan(110.68×0.425)
=90-arctan3.99925-arctan0.425-arctan0.2125-arctan47.039
=90-1.325774-arctan0.425-arctan0.2125-arctan47.039
=90-1.325774-0.401871-arctan0.2125-arctan47.039
=90-1.325774-0.401871-0.209385-arctan47.039
=90-1.325774-0.401871-0.209385-1.549541
=88.674226-0.401871-0.209385-1.549541
=88.272355-0.209385-1.549541
=88.06297-1.549541
=86.513429
Answer:90-arctan(9.41×0.425)-arctan0.425-arctan(0.5×0.425)-arctan(110.68×0.425)=86.513429
