r cos(t) =10
r = 10/cos(t)

well, x = r cos(t) thats just by definition

so, r cos(t) = 10 is a direct translation to polar form

yes; t = theta ... it really doesnt matter what you call it, it never comes when called

ohh ok thanks i was just checking because i was confused. anyways so the answer is r=10/cos theta

maybe, i cant remember if the divide by 0 applies to mess things up with

I know to get a straight line; which is what x=10 is; you keep the theta a constant... but id have to read up on it again

i think tthe answer is right because some of my other answers ended with r=///// so it should be right hold on no the answer is r=10 sec theta

r = sec and 1/cos are the same thing

\[sec = \frac{1}{cos}\]

\[\frac{10}{cos}=10 sec\]
