Please show how
v1^2 = (s^2*v^2)/(s^2+nv^2)
and m1 = (s^2m + n*(v^2)x)/((s^2)+nv^2)
every single step is not necessary just the important ones.
An expression is simplified. The solution is detailed and well presented. The response received a rating of "5/5" from the student who originally posted the question.
