1.- Plot question Let the differential equation: In[]: Y[x_]=y[x]/.First[DSolve[y[x]-1/2 x y'[x]==0,y[x],x]] Out[]: Subscript[c, 1] x^2 In[]: Plot[Y[x]/.C[1]->20,{x,-2,2}] And yields a correct graphic. But In[]: Yort[x_]=y[x]/.First[DSolve[y[x]-1/2 x (-1/y'[x])==0,y[x],x]] Out[]: -(Sqrt[4 Subscript[c, 1]- x^2]/Sqrt[2]) And yields nothing. 2.- Menu options question The menu options of Edit\CopyAs are PlainText, InputText, ... Bitmap, Metafile But, the menu options of secundary bottom mouse of CopyAs are PlainText, Cell Expression, Notebook Expression . I think that is very useful al options on the secundary mouse.
