Question

Does anyone have any idea why when I graph cos(x) in the Ti Nspire, it just graphs me a straight line?

Answer 1

Same with sin(x) and all other trigs :/

Answer 2

you in rad?....

Answer 3

It does the same thing in both rad and degree.. :(

Answer 4

perhaps you assigned x to be a fixed number, like x = 2. Or maybe you're using the wrong input variable.

Answer 5

nope, that's not it either.. It was working fine yesterday and it just suddenly started doing this

Answer 6

try resetting your calc... although you may lose some data
