Work: Calculate the value of equation -arctan(13.1/(-5.7))-arctan(13.1/(5-5.7))-arctan(13.1/(20-5.7)) .
Question type: Mathematical calculation
Solution:
-arctan(13.1/(-5.7))-arctan(13.1/(5-5.7))-arctan(13.1/(20-5.7))
=-arctan(13.1/(-5.7))-arctan(13.1/(5-5.7))-arctan(13.1/(20-5.7))
=-arctan(-2.298246)-arctan(13.1/(5-5.7))-arctan(13.1/(20-5.7))
=-arctan-2.298246-arctan(13.1/(-0.7))-arctan(13.1/(20-5.7))
=-arctan-2.298246-arctan(-18.714286)-arctan(13.1/(20-5.7))
=-arctan-2.298246-arctan-18.714286-arctan(13.1/14.3)
=-arctan-2.298246-arctan-18.714286-arctan0.916084
=--1.16039-arctan-18.714286-arctan0.916084
=--1.16039--1.517412-arctan0.916084
=--1.16039--1.517412-0.741631
=1.517412-0.741631
=0.775781
Answer:-arctan(13.1/(-5.7))-arctan(13.1/(5-5.7))-arctan(13.1/(20-5.7))=0.775781
