A) Having memory. The function y(t) = sin(x(t-1)) has memory because it depends on the previous value of x(t). The value of x(t-1) affects the output of y(t), so it has a memory of the past values of x(t).

b) Needing memory. Since y(t) = sin(x(t-1)) depends on x(t-1), it requires the past value of x(t) to be stored or remembered in order to compute the current value of y(t). Therefore, it needs memory to keep track of the previous value.
