Let f(x, y) = x sin(x² + y) +x+y for z, y € (-00, 00). Which of the following statement is true? (a) 9² (b) f(x, y)dy = -x cos(z² + a) + x cos(x²) + ax + for a > 0. 2 f(x,y) lim (2,3)+(0,0) x(x² + y) = 1. (c)f(x, y) = 2x² cos(x² + y) + sin(x² + y) + 1. (d) The tagent planc to the surface z = f(x, y) at the point (0,0,0) is z = 2x + y. (e) None of the above statements is truc.
