I am planning to use Mathcad prime Express in my development calculation after 30 days of my Mathcad prime trail completion.
So, I would like to know whether or not Mathcad prime express supports simple exponential calculation,
Sin, Cos function or not and their graph or not?
exp, trig functions and 2D-plots will work in Express mode, too, given that on contrary to your screenshot you use correct syntax.
You can test it yourself while you are in full evaluation mode, too. Simply point the license manager to any existing file (which is not a valid license). Your installation will switch to express mode. later point the license manager back to the valid license file.
