Format . The letter e will be recognised as Euler's number. . Use * to explicitly indicate multiplication between variables and other variables, between variables and brackets (e.g. x*y rather than xy; 2*(x+y) rather than 2(x+y)) . Put arguments of functions in brackets (e.g. sin(x) rather than sin x) . Give your answers in exact form. You are given that 4x2 . z + 2y . In(x) - 2+3 =0. Here a is a function of independent variables y and z. a. Find in terms of c, y and z. Ox ( x , y, z ) = f
