Question

amistre64 · Answer

(10,0)

amistre64 · Answer

oh, the equation, not the point lol

anonymous · Answer

yeah haha could you please show the work? thank you

amistre64 · Answer

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

anonymous · Answer

where did u get t from?

amistre64 · Answer

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

amistre64 · Answer

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

anonymous · Answer

do you mean theta?

amistre64 · Answer

i dont think I did the divide right tho

amistre64 · Answer

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

anonymous · Answer

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

amistre64 · Answer

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

anonymous · Answer

im not sure either its quite confusing

amistre64 · Answer

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 · Answer

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 · Answer

how do you get secant?

amistre64 · Answer

r = sec and 1/cos are the same thing

amistre64 · Answer

$$sec = \frac{1}{cos}$$

amistre64 · Answer

$$\frac{10}{cos}=10 sec$$

anonymous · Answer

i see thanks so much for your explanations

youre welcome :)
