a) () is for grouping. Function arguments are in square brackets, []. See

b) For ordinary input, Mathematica function names begin with capital letters.

c) The function "head" or pattern on the left is better with dummy arguments that can stand for any argument. See
http://reference.wolfram.com/mathematica/tutorial/DefiningFunctions.html

u(x,t) = [sin(4x) + cos(2x)] [cos(t) + sin(t)]
brcomes

u[x_,t_] = (Sin[4x] + Cos[2x]) (Cos[t] + Sin[t])
