Solve across an interval

[lrdheat]

Help for solve shows the possibility of searching for solutions within an interval using the syntax "a..b" When passing the example given in help to the command line and executing, the calculator produces an error relating to syntax. Is it possible to search for solutions over an interval?

Somewhat related, when using advanced graphing app and numerical table to show multiple solutions "X" for a given f(X), there are functions that take a lot of time to graph that result in the table not filling, yet the function graphs immediately in regular graphing app. An example is a function I had a thread on recently...

((Sqrt(tan X + 1)-sqrt(sin X + 1))/x^3
