When I input this in matlab it does not run.

@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?

Answer 2

[James Tursa]

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

Answer 3

[RAVI Kumar]

Thetha=pi/4
