Please answer the following question completely, I will upvote.
![A random process X (t) is defined as
X(t) = A. cos(27 fd)+A, sin(27fdt)
where A, and A, are independent Gaussian random variables with zero mean and variance o? and
o, respectively, where o? = o? = o?.
(a) Find the mean E[X].
(b) Find autocorrelation function Rx(t+T,t).
