I've been through my mode pletty of times trying to figure it out. Okay here are a couple examples of what I'm getting.

input -> solve(tan(x)=1,x) ans-> x=45*(4*@n22+1)

input -> solve(sin(x)=.5,x) ans-> x=360*(@n21(pi)=1.308997)/(pi) or x=360*(@n21(pi)=.2617994)/(pi)

I don't have anything stored for x. If i input x , then enter I get x as the result.

Please HELP!!! Thank you!
