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 
thank you, now I understand
