Calculating the value for cotangent.

**My question says to "calculate the value for cotangent (0) if (0)=270 degrees, given in standard position"**

Just calculating it and getting 1.8370 I got it counted wrong, and when I asked on another forum about it they had gone through and what seems like to me, they used quotient identities and put the cos(270)/(sin(270) to equal 0.

Is that the right way to go about this? It didn't say to use quotient identities so I wasn't sure.

There's a second question with the same degree but its asking for the csc (cosecant) of 270, given in standard position.

Ah, alright, thanks for verifying :)

sec(270) would be -1 then.

Yes!(But only by my definition of sec function)(Crying)

No!

sec(270)=1/cos(270)=1/0

But the question doesn't ask for , it asks for .
