Homework Help: Math repost

Posted by Amy on Tuesday, March 1, 2011 at 10:13pm.

I posted this question before at 7:14
I think the answer to it is 0.
cot(40) - ((sin(50))/(sin(40)) = ?
these are also degrees
steps too please.

I thought since 50+40= 90 then that part would be 1, but then how would cot 40 turn out to be 1

sin50=cos40

then

ctn(40)-cos/sin= ctn(40)-ctn(40)=zilch
