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

where did u get t from?
amistre64
  • amistre64
well, x = r cos(t) thats just by definition
amistre64
  • amistre64
so, r cos(t) = 10 is a direct translation to polar form

do you mean theta?
amistre64
  • amistre64
i dont think I did the divide right tho
amistre64
  • amistre64
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
amistre64
  • amistre64
maybe, i cant remember if the divide by 0 applies to mess things up with
anonymous
  • anonymous
im not sure either its quite confusing
amistre64
  • amistre64
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
anonymous
  • anonymous
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
anonymous
  • anonymous
how do you get secant?
amistre64
  • amistre64
r = sec and 1/cos are the same thing
amistre64
  • amistre64
\[sec = \frac{1}{cos}\]
amistre64
  • amistre64
\[\frac{10}{cos}=10 sec\]
