Question

how do you convert y=2x-1 to polar form???

Answer 1

\(\bf \textit{keep in mind that }x=rcos(\theta)\qquad y=rsin(\theta)\qquad thus\\ \quad \\
y=2x-1\implies rsin(\theta)=2[rcos(\theta)]-1\)

solve for "r"

Answer 2

so i finished the problem but I'm not sure if it is right.

is the answer 1/2cos-sin=r???

Answer 3

1/2cos-sin=r \(\checkmark\)

Answer 4

yes \(\bf \cfrac{1}{2cos(\theta)-sin(\theta)}=r\)

Answer 5

thanks a lot
