Work: Calculate the value of equation arctan(0.15*18.72)+90-arctan(0.2*18.72)-arctan(0.02*18.72)-arctan(0.0625*18.72) .
Question type: Mathematical calculation
Solution:
arctan(0.15*18.72)+90-arctan(0.2*18.72)-arctan(0.02*18.72)-arctan(0.0625*18.72)
=arctan2.808+90-arctan(0.2*18.72)-arctan(0.02*18.72)-arctan(0.0625*18.72)
=arctan2.808+90-arctan3.744-arctan(0.02*18.72)-arctan(0.0625*18.72)
=arctan2.808+90-arctan3.744-arctan0.3744-arctan(0.0625*18.72)
=arctan2.808+90-arctan3.744-arctan0.3744-arctan1.17
=1.228675+90-arctan3.744-arctan0.3744-arctan1.17
=1.228675+90-1.309795-arctan0.3744-arctan1.17
=1.228675+90-1.309795-0.358245-arctan1.17
=1.228675+90-1.309795-0.358245-0.863579
=91.228675-1.309795-0.358245-0.863579
=89.91888-0.358245-0.863579
=89.560635-0.863579
=88.697056
Answer:arctan(0.15*18.72)+90-arctan(0.2*18.72)-arctan(0.02*18.72)-arctan(0.0625*18.72)=88.697056
