Hello all,
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.
The parameter increments by 1 every time it is used (to distinguish it from the previous parameters).
The equation you solved above is over a fininte domain and there is a finite number of solutions. The calculator can tell you each one. In the previous examples you were solving over an infinite domain and there were an infinite number of solutions, these solutions are represented using a parameter.
