Question

Find the characteristics equation of yz (dz/dx) + zx (dz/dy) = xy​

Answer 1

Answer:

dz/dx(yz)+dz/dy(zx)= 0+0=0 Thus, xz=0

Step-by-step explanation:

in the derivative of x, there is no x in yz thus making it constant and so is the case with zx. We know that dy/dx(constant function)= 0. Thus, giving us our answer. Hope, it helps you.
