If f (x) = e x 3 + 4 x, find f ′′ (x) and f ′′′ (x), 2 nd and 3 rd order derivatives of f (x). 3. WebThe derivative of a function describes the function's instantaneous rate of change at a certain point. Another common interpretation is that the derivative gives us the slope of …
WebYes you are correct that the derivative of -sinx is -cosx. d/dx means "the derivative of, with respect to x". So for example, d/dx (-sinx) = -cosx.
