Work: Calculate the value of equation 286.561×(tan(45-16.13/2)*tan(45-16.13/2))-2×12.87×tan(45-16.13/2) .
Question type: Mathematical calculation
Solution:
286.561×(tan(45-16.13/2)*tan(45-16.13/2))-2×12.87×tan(45-16.13/2)
=286.561×(tan36.935*tan(45-16.13/2))-2×12.87×tan(45-16.13/2)
=286.561×(tan36.935*tan36.935)-2×12.87×tan(45-16.13/2)
=286.561×0.918356-2×12.87×tan(45-16.13/2)
=286.561×0.918356-2×12.87×tan36.935
=286.561×0.918356-2×12.87×-0.958309
=263.165014-2×12.87×(-0.958309)
=263.165014-25.74×(-0.958309)
=263.165014-(-24.666874)
=287.831888
Answer:286.561×(tan(45-16.13/2)*tan(45-16.13/2))-2×12.87×tan(45-16.13/2)=287.831888
