PART C
help pls <@&791435371564892232>
I do not understand how to find the domains and ranges when t has a boundary, sometimes I get it wrong and I don't understasnd the ms.
How do you answer these qs?

the domain is all the x values you can achieve in the given interval of t

#

so you have to find what values of $x$ you can get by plugging in values of $t$ into $x=2\cot t$
