Question 1065241: Hello! I hope you are having a wonderful day. I have a question that I am not too sure about.
What is the domain of the function y=tan x
The possible answers are
1. All real numbers
2. All real numbers except n90° degrees for all integers n
3. All real numbers except 90° degrees + n180° for all integers n
4. All real positive numbers

You can put this solution on YOUR website!
Looks like (3) to me. +y+=+tan%28x%29+ will give you
back a +y+ for any +x+ EXCEPT +x+=+90+
or +x+=+270+.
If you keep adding +180+ to +90+, that will
keep returning you to +90+ or +270+ where
the tangent function is infinite.
Hope this helps
