MATLAB: Where is the mistake

Question

I'm trying to get this anonymous function to work bur no matter how I do it it keeps telling me that there is something wrong with the parenthesis or brackets. What can I do to fix this?

a=45; g=9.82; v=9.0;

>> throwfun = @(x) x.*tan(a)-((g*x.^2)/(2(v*cos(a))^2));

Error: Unbalanced or unexpected parenthesis or bracket.

Answer 1

You missed the * after 2 in the last terms

use

throwfun = @(x) x.*tan(a)-((g*x.^2)/(2*(v*cos(a))^2));
