Section 13: Solving Trigonometric Equations(TI-89)
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·@n9·π+1,02862...
Rather than a number. Does anyone know what the problem is?
Any help much appreciated!
