I'm trying to define the function
t=1:1/8000:5
x(n)=sin(2*pi*t(n))
I've tried function x(n)=sin(2*pi*t(n)) like you would do in the editor but it doesn't work. What's the correct sintax?

At the command window, you can use
x = @(n) sin(2*pi*t(n));
This will create the function named "x" that takes a single parameter, n.
Note that this function will not be available within other functions unless it is passed as a parameter to the other function: its definition will be local to the scope it is in.

Functions can be defined in M-files only. In addition these M-files must be functions itself, so scripts are not allowed. And an M-file is a function, if it starts with the term "function".
Reading the Getting Started chapters of the documentation is obligatory, when you want to use such a powerful tool as Matlab.

t=1:1/8000:5;
x =sin(2*pi*t);
Have you tried to read the MATLAB documentation?
