Talk:Solve Command
From GeoGebra Manual
When solving a trigonometric equation, such as sin(x)=0.3, 0<x<2π, it is not possible to solve it using Solve[sin(x)=0.3, 0<x<2π]. It is required to use " {" and "}" in order to solve it --> Solve[{sin(x)=0.3, x>0, x<2π}]. I think this should be mentioned on the "Solve Command" help page.
