It is the same as the first. / = ( (log))/ / = 1/ Again Differentiating / (/) = ( )/ (1/) (^2 )/ (^2 . It can also be considered as a composite function where x is algebraic and 2 is a constant. To prove you may exchange summation and differentiation, it suffices to prove that the second series (the series of derivatives) converges uniformly (locally uniformly is also good). The derivative formula of xsin x is given below: d dx (xsinx) d d x ( x sin x) = sinx + xcosx = sin x + x cos x. \[\frac{d}{dx} {e}^{x}\cos{x}\] +. Yes that is the general equation for the nth derivative of sine the second thing is pi, not another n. The second thing is the chain rule Your question can be answered by combining these two. that z was equal to two separate differentials and integrate the first part of the function with respect to x and the second part with respect to y? Here you can see the derivative f'(x) and the second derivative f''(x) of some common functions. A similar thing happens between f'(x .
