1. ## cot on calculator?

cot 0.2674

I have a scientific calculator. I'm not entirely sure how to do this. Can someone tell me if they know the sequence to enter or if easier (because of variance in calculators) just tell me the answer and I can guess and check until I figure it out.

I know I enter a combo of tan 1/x or tan^-1

thanks soo much

Shift or 2nd Function -> Tan -> 0.2674 -> Equals

How much easier can it be?

It wouldn't be arctanx

4. When I do that I get 14.97 and that isn't right though. hmm?
Thanks much.

Hi janvdl! I don't think that would work since he wants the cotangent. I assuming he is having problens because a scientific calc does not have a cot key like a graphing calc does.

6. Im using a TI-36X
Hmmm. I wonder..

Note that cot x = 1 / (tan x)

So if your calculator has the tan button, hit:

1 / tan (.2674)

Oh yes, high school trig class 1...

cot x = 1 \ tan x

(Dang you Chris! )

9. $\frac{1}{\tan{x}} = \cot{x}$

Edit: Chris beat me to it.

10. It has the tan button. But what do you mean by 1/tan?
Do you mean hit 1/x and then tan? because thats not working either. thanks so much.

Press:

tan -> 0.2674 -> equals -> then take it to the power of -1

Haha...no worries. This kind of thing happens to me ALL the time on MHF (where someone beats me by a minute)... especially the one where two posts appear at the same time
