syms theta
2*sin(theta)
Then by substituting theta with any numeric variable, you can calculate 2*sin(theta)

@Courtney: "It does not run" does not allow to help you. Please post, what happens instead - perhaps an error message because you do not have the Symbolic Toolbox?

E.g.,
theta = pi/4;
result = 2*sin(theta); % <-- if theta is in radians
theta = 45;
result = 2*sind(theta); % <-- if theta is in degrees
