If you are taking the partial with respect to y treat x as a constant, and just take a derivative as you normally would, if you need me to do the rest I can.2) d/dx = (y sec(y) (x cos(x)-sin(x)))/x^2 d/dy = (sin(x) (y tan(y)+1) sec(y))/x d^2/dy^2= (sin(x) sec(y) (tan(y) (y tan(y)+2)+y sec^2(y)))/x d^2/dx^2= -(y sec(y) ((x^2-2) sin(x)+2 x cos(x)))/x^3 d/dx (d/dy)= d/dy (d/dx) = ((y tan(y)+1) sec(y) (x cos(x)-sin(x)))/x^2
