1. ## Urgent how to differtiate a formule with TI89

hey guys

I got a math test tommorow and i need to know how i can differentiate with the Ti89.I already know how to solve formules but not how to differentiate. so i mean like x^2=x when its differentiated

2. Hello,

To differentiate a function, use F3-1

It's a special d

d(x^2,x)=2x

EDIT : i'm not sure i've understood well the question o.O
