Work: Calculate the value of equation arctan(66/(-0.2*88+1))-arctan(66/(-0.02*88+1))-arctan(-90*1.732/65)-arctan(-90*1.732/115) .
Question type: Mathematical calculation
Solution:
arctan(66/(-0.2*88+1))-arctan(66/(-0.02*88+1))-arctan(-90*1.732/65)-arctan(-90*1.732/115)
=arctan(66/(-16.6))-arctan(66/(-0.02*88+1))-arctan(-90*1.732/65)-arctan(-90*1.732/115)
=arctan(-3.975904)-arctan(66/(-0.02*88+1))-arctan(-90*1.732/65)-arctan(-90*1.732/115)
=arctan-3.975904-arctan(66/(-0.76))-arctan(-90*1.732/65)-arctan(-90*1.732/115)
=arctan-3.975904-arctan(-86.842105)-arctan(-90*1.732/65)-arctan(-90*1.732/115)
=arctan-3.975904-arctan-86.842105-arctan(-2.398154)-arctan(-90*1.732/115)
=arctan-3.975904-arctan-86.842105-arctan-2.398154-arctan(-1.355478)
=-1.324392-arctan-86.842105-arctan-2.398154-arctan-1.355478
=-1.324392--1.559282-arctan-2.398154-arctan-1.355478
=-1.324392--1.559282--1.175732-arctan-1.355478
=-1.324392--1.559282--1.175732--0.935183
=0.23489-(-1.175732)-(-0.935183)
=1.410622-(-0.935183)
=2.345805
Answer:arctan(66/(-0.2*88+1))-arctan(66/(-0.02*88+1))-arctan(-90*1.732/65)-arctan(-90*1.732/115)=2.345805
