SUMMARY

The discussion focuses on calculating the variable M in the equation -3.2 = -M(5)e^(-0.02)(0.8)[377cos(377*0.08)-(0.025)sin(377*0.8)]. The solution provided indicates that M equals 1.73. To arrive at this result, participants emphasize the importance of first calculating the expression e^(-0.025)(0.8)[377cos(377*0.08)-(0.025)sin(377*0.8)], followed by dividing the outcome by 5 to isolate M.

Please break down how this solution was reached for me.

-3.2=-M(5)e^-((0.025)(.8))[377cos(377*0.08)-(0.025)sin(377*0.8)]
M=1.73

Thank you soo much!

Calculate e^-((0.025)(.8))[377cos(377*0.08)-(0.025)sin(377*0.8)] first.

then just divide by that answer and then divide by 5.
