How would you type: -6cosec^2 t where t = pi/4

Into a calculator? I've tried but i keep coming up with the wrong answer.

-6cosec^2(pi/4)

Yeah i've got it in radians mode. So baiscally i do pi /4 (giving me a number). Then square it, then do sin of it. Then do 6 divided by that answer?

Although personally, I wouldn't be using my calculator for that - I'd note that sin(pi/4) = 1/root2.
