  1. I'm doing some basic trigonometry, and when i use any sin-1, cos-1 or tan-1 functions, i get ERR: DOMAIN.
    I've reset it entirely, put the mode onto DEGREE, and i"m still getting an error message.
    It was working fine yesterday, and I've got my math practice exam tomorrow, and it shit out on me tonight. Can anyone help, like ASAP?

    Give me problem and I'll figure out, I have a TI-84. The problem is in the the error itself, the domain. A value you entered in any of the trigonometric inverse functions is outside of the domain.

    This explains it because I'm too lazy to teach a math lesson.
