Work: Calculate the value of equation -5*0.3*sin240-40/3*0.2*sin300-10*0.3*sin30 .
Question type: Mathematical calculation
Solution:
-5*0.3*sin240-40/3*0.2*sin300-10*0.3*sin30
=-5*0.3*0.945445-40/3*0.2*sin300-10*0.3*sin30
=-5*0.3*0.945445-40/3*0.2*-0.999756-10*0.3*sin30
=-5*0.3*0.945445-40/3*0.2*-0.999756-10*0.3*-0.988032
=-1.5*0.945445-40/3*0.2*(-0.999756)-10*0.3*(-0.988032)
=(-1.418168)-40/3*0.2*(-0.999756)-10*0.3*(-0.988032)
=-1.418168-13.333333*0.2*(-0.999756)-10*0.3*(-0.988032)
=-1.418168-2.666667*(-0.999756)-10*0.3*(-0.988032)
=-1.418168-(-2.666016)-10*0.3*(-0.988032)
=-1.418168--2.666016-3*(-0.988032)
=-1.418168--2.666016-(-2.964096)
=1.247848-(-2.964096)
=4.211944
Answer:-5*0.3*sin240-40/3*0.2*sin300-10*0.3*sin30=4.211944
