1. After I launch the "Home" program and enter(adsbygoogle = window.adsbygoogle || []).push({});

d(x^2,x)

The calculator spits out -52.4916, a numerical solution. What I want is the algebraic derivative2x- how do I get to the algebraic derivative?

2. When I enter sin(60), it gives me -0.304811 as an output. Why does the Ti-89 give a negative result, while the Ti-83 provides me with a positive one?

Sorry if I'm in the wrong forum. The forum search didn't spit out anything.
