## animalsavior94 Group Title convert the rectangular equation to polar form. assume a is less than 0. x=10 3 years ago 3 years ago

1. amistre64 Group Title

(10,0)

2. amistre64 Group Title

oh, the equation, not the point lol

3. animalsavior94 Group Title

yeah haha could you please show the work? thank you

4. amistre64 Group Title

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

5. animalsavior94 Group Title

where did u get t from?

6. amistre64 Group Title

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

7. amistre64 Group Title

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

8. animalsavior94 Group Title

do you mean theta?

9. amistre64 Group Title

i dont think I did the divide right tho

10. amistre64 Group Title

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

11. animalsavior94 Group Title

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

12. amistre64 Group Title

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

13. animalsavior94 Group Title

im not sure either its quite confusing

14. amistre64 Group Title

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

15. animalsavior94 Group Title

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

16. animalsavior94 Group Title

how do you get secant?

17. amistre64 Group Title

r = sec and 1/cos are the same thing

18. amistre64 Group Title

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

19. amistre64 Group Title

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

20. animalsavior94 Group Title

i see thanks so much for your explanations

21. amistre64 Group Title

youre welcome :)
