Ok everyone knows that 1/square root of 3 needs to be rationalized... if you have a ti84+ with os 2.55 type the following & ps back up your calc.
Now type 3/sqroot of 3 and press enter...
If it did what my calc did you just saw some thing crazy... eathere a ram clear or blue lines of death both or just the graph screen.
6/sqroot of 3 will turn your calc into horizontial mode with out the line and opens the graph screen fist it splits the screen putting the top on the bottom.
See what you can do! Ps back up! Also this only works for sqroot of three.
Not responsible for lost files or crashed calcs.
Have funalso if any guru's know why please explain
