Is it possible to automatically (from command line, or using select and then the menu from right-click of the mouse) to isolate specific terms in an equation withn maple? Hier is a very simple simple example example (may equations are way too large):
$\frac{\sqrt{a1-b^2}}{c}+d-e=0$ and say I want to get $\frac{\sqrt{a1-b^2}}{c}=-d+e$
for my equation, I already tried the command idolate but it seems not to work very cleverly
By "isolate", do you mean you want to get this particular term as an expression? If you can select it with the mouse, you can copy it either from the right-click menu or by keyboard command (Ctrl+C for Linux or Windows, Command+C for Mac) and then paste it into an input line (Ctrl+V for Linux or Windows, Command+V for Mac).
UPDATE: In your example, you want to use the command "isolate". Given the equation (call it "eq"), and your term "term" the command
should produce exactly what you asked for:
$$ {\frac {\sqrt {a1 -{b}^{2}}}{c}}=-d+e$$
Please be more explicit about in what sense this "seems not to work very cleverly"/
