express 10*sin*w.t in the form A*sin*w.t + B*sin*w.t
It is already in the form you want. Just set A = 10 and B = 0.
To express the expression 10*sin(wt) in the form A*sin(wt) + B*sin(wt), you can rewrite it as:
A*sin(wt) + B*sin(wt)
Since the expression is already in the form of sin(wt), you can set A = 10 and B = 0:
10*sin(wt) + 0*sin(wt)
This simplifies to:
10*sin(wt)
So the expression 10*sin(wt) is already in the form A*sin(wt) + B*sin(wt), where A = 10 and B = 0.
