You probably mean either of these:
% if x is in radians:
tan(45+x/2).^2
% if x is in degrees:
tand(45+x/2).^2
If you don't, please explain in a comment to your question what you mean mathematically.

That 45 in the expression makes me suspect bruk tgsetu is working in degrees, in which case they should use the degree-based tangent function tand instead of the radian-based tan.

Good point. I've edited my answer to include that point.
