MATLAB assumes that symbols might have complex values unless you tell it they are not complex. For complex values, sqrt (x^2) is not the same as x. For that matter, sqrt (x^2) is not the same as x even just for negative real values. If you know for sure that your values are nonnegative, then add an assumption about …The Symbolic Math Toolbox™ currently does not support composite symbolic functions, or symbolic functions that are functions of another symbolic functions.
