If ω & A are constant then d[ω√(A^2 - x^2)]/dt =?
A) ω/{2√(A^2 - x^2)}
B) -ω/{2√(A^2 - x^2)}
C) -ωx/{√(A^2 - x^2)}
D) None of these
Can u please explain the reasoning too?
We do not know for sure that is constant, so you should leave it in a form involving . If happens to be constant the derivative will still work out to be 0.
So in this case, assuming you typed the problem correctly and we are differentiating with respect to , (D) would be correct.
