I can't find how to solve the simle problem sec B= 1.0768 ?
The solution for Graphing Calculator is Cos‾¹ ( 1.0768 ) x‾¹ ) ENTER
the problem is that TI_89 does not contain a botton x‾¹ ? How can I substitute it? |

Hi Molly,
Welcome to TI-89.org forums.
x^-1 is just a fancy way of saying 1 / x. You can just type cos^-1(1/1.0768) to get your answer.
Hope this helps.
