    Trig functions on TI-89 Titanium

    Hey guys,

    I have a problem with my TI-89 titanium. I'm currently doing some trig functions and the answer to some of the equations are
    looking quite strange to me. For instance, if i plug in:

    cos(x)=0.516,x in solve,

    I get this:

    2@n9π+1,02862...

    Rather than a number. Does anyone know what the problem is?
    Any help much appreciated!
