dY/dX = X/Y Given a budget constraint, with positive prices for both, the consumer would maximize utility by purchasing only X. On the other hand, if we framed the problem in terms of Y removal, then U = (X2+Y2).5 as we established in the part c, the MRS for such a problem–X/Y exhibits an increasing MRS.

The optical flow equation is fx(x,y) dx(x,y) + fy(x,y) dy(x,y) + ft(x,y)=0, where fx(x,y) = spatial gradient in x direction at pixel (x,y), fy=spatial gradient in y direction at pixel (x,y), ft= f2(x,y)-f1(x,y) is the temporal gradient. To solve for the motion parameters utilizing the optical flow equation, we solve the following optimization ...

y = ln x . We could re-write the equation in exponential form: e y = e ln x . e y = x . Next, we can find the derivative using implicit differentiation: e y dy dx = 1 . Then, we can solve for . dy dx : dy dx = 1 e y . Furthermore, we can substitute for ‘y’ since y = ln x : dy dx = 1 e ln x . Finally, this simplifies: dy dx = 1 x
