Work: Calculate the value of equation 2*cos(2.2)*sqrt((215+215*cos4.39-2*esin4.39)/2*215) .
Question type: Mathematical calculation
Solution:
2*cos(2.2)*sqrt((215+215*cos4.39-2*esin4.39)/2*215)
=2*cos2.2*sqrt((215+215*cos4.39-2*esin4.39)/2*215)
=2*cos2.2*sqrt(146.106247/2*215)
=2*cos2.2*sqrt15706.421445
=2*-0.588501*sqrt15706.421445
=2*-0.588501*125.325263
=-1.177002*125.325263
=(-147.508085)
Answer:2*cos(2.2)*sqrt((215+215*cos4.39-2*esin4.39)/2*215)=-147.508085
