From math class, some trigonometric identities:
cot x = 1/tan x
csc x = 1/sin x
sec x = 1/cos x
There are no built-in cot or csc formulas, so use the above.
Remember that these give errors when tan x, sin x, or cos x are equal to 0.

tan cot sec cosec sin cos cot
The TI-83 does not have the cot button, however, if you type 1/tan( then this will work the same as the cot since cot=1/tan. The other way to do this is to type (cos(x))/(sin(x)) where x is the angle you're looking for. This works because cot=cos/sin
d/dx (cot x) = -csc2x
plz send me cot code
The word cot has one syllable.
