However, in some cases, Simplify is really stubborn, so you will need to apply a rule directly with ReplaceAll. See also MultiplySides and the like. | |

This might require assumptions so that the sine is never unity. Refine and Simplify in tandem seem to manage it then. In[76]:= ee = Cos[\[Theta]] ((Sqrt[-((g H)/(-1 + Sin[\[Theta]]))] Sqrt[-g H (-1 + Sin[\[Theta]])])/ g - (H Sin[\[Theta]])/(-1 + Sin[\[Theta]])); Simplify[Refine[ee, Assumptions -> {g > 0, H > 0, 0 < \[Theta] < Pi/2}], Assumptions -> {g > 0, H > 0, 0 < \[Theta] < Pi/2}] Out[77]= (H Cos[\[Theta]])/(1 - Sin[\[Theta]])
