I just started having a problem with my TI-89 titanium. Wondering if any of you can help me out. Whenever I try and solve for an angle it gives me some funky answers, I don't get it. 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!
It just started doing this... It has never done this before. It has a count going on in that answer. Each time the end half dislplays some type of (4*@n22+1) then next time would be (4*@n23+1), then (4*@n24+1) and so on. I've had this calculator for almost a year and I promise this is not normal.
