Work: Calculate the value of equation 314×(tan(45-15.738/2)*tan(45-15.738/2))-2×12.827×tan(45-15.738/2) .
Question type: Mathematical calculation
Solution:
314×(tan(45-15.738/2)*tan(45-15.738/2))-2×12.827×tan(45-15.738/2)
=314×(tan37.131*tan(45-15.738/2))-2×12.827×tan(45-15.738/2)
=314×(tan37.131*tan37.131)-2×12.827×tan(45-15.738/2)
=314×0.407437-2×12.827×tan(45-15.738/2)
=314×0.407437-2×12.827×tan37.131
=314×0.407437-2×12.827×-0.638308
=127.935218-2×12.827×(-0.638308)
=127.935218-25.654×(-0.638308)
=127.935218-(-16.375153)
=144.310371
Answer:314×(tan(45-15.738/2)*tan(45-15.738/2))-2×12.827×tan(45-15.738/2)=144.310371
