3. Using the definition of limit show that: lim czy = 4 (I,y)+(2.2) [15 marks] = 4. Let = (y, z), y = y(x, z), 2 = 2(1, y) be functions, defined by the equation F(x, y, z) 0. Show that дz ду дz az ar ay Hint: Assumer (y, 2) then from the equality F(x(y, z), y, z) = 0 find out similarly assuming y= y(x,z) from F(x, y(x,z), z) = 0 obtain etc...... [5+5+5=15 marks] -1 = = az
