in a separation of variables problem you find that makes sense. What can you conclude? A' (t) A(t) y'(x) for all and t where this T A. The function A'(t)/A(t) must be constant but not necessarily the function y(x)/y(x). B. The function "(z)/y(z) must be constant but not necessarily the function A'(t)/A(t). C. Both A'(t)/A(t) and y'(r)/y(r) must be constant but not necessarily the same constant. D. Both A'(t)/A(t) and y"(x)/y(r) must be constant and equal to the same constant.
