# Math repost

posted by .

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

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

• Math repost -

sin50=cos40

then

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

thank you, now I understand
