Question

How do I convert this to Cartesian
http://prntscr.com/ai9hsf

Answer 1

i am only confident in converting polar to cartesian . This is a roundabout way of solving this but lets try one of the options r = 4 cos O

multiply both sides by r
r^2 = 4 r cos O

now we use r^2 = x^2 + y^2 and x = r cos O and substitute in the above

x^2 + y^2 = 4x

x^2 + y^2 - 4x = 0

Answer 2

so its the first option
r = 4 cos O

Answer 3

OK?

Answer 4

okay

Answer 5

I felt the same way but was shakey on how to go from Cartesian to polar. Thank you though :)
