In the equation of forced oscillations (given below),
ma = -kx + FCoswt, why is that the 2nd term on the right hand side is given the +ve sign. I know that kx should be negative since 'ma' and 'x' are in opposite directions. I can't quite seem to get the gist of Fcoswt being given a +ve sign. Can someone clarify?
