Hi Mathematica community,
I try to use Case[exp,patt,Infinity]
for the first example it works:
Cases[iP == i + v && kaP == 3^v, iP == _ | kaP == _, Infinity]
the output is {iP == i + v, kaP == 3^v}
but not for the second one!!
Cases[yP == y + x - z, yP == _, Infinity]
the output is {}
why?!!
Thank you.
