Short Answer

Identify the curve by finding a Cartesian equation for the curve.
\({\rm{\theta = }}{{\rm{\pi }} \mathord{\left/
{\vphantom {{\rm{\pi }} 3}} \right.
\kern-\nulldelimiterspace} 3}\)

The curve is\({\rm{y = }}\sqrt {\rm{3}} {\rm{x}}\).

Step 1: Find a Cartesian equation for the curve and use it to identify it.

Given: \({\rm{\theta = }}\frac{{\rm{\pi }}}{{\rm{3}}}\)

Take the tan from both sides and combine them.

\({\rm{tan\theta = tan}}\frac{{\rm{\pi }}}{{\rm{3}}}\)

Known value, \({\rm{tan\theta = }}\frac{{{\rm{sin\theta }}}}{{{\rm{cos\theta }}}}\)

\(\frac{{{\rm{sin\theta }}}}{{{\rm{cos\theta }}}}{\rm{ = }}\sqrt {\rm{3}} \)

Both the numerator and denominator should be multiplied by\({\rm{r}}\).

\(\frac{{{\rm{rsin\theta }}}}{{{\rm{rcos\theta }}}}{\rm{ = }}\sqrt {\rm{3}} \)

Keep in mind that: \({\rm{rcos\theta = x\& rsin\theta = y}}\)

\(\begin{aligned}{l}\frac{{\rm{y}}}{{\rm{x}}}{\rm{ = }}\sqrt {\rm{3}} \\{\rm{y = }}\sqrt {\rm{3}} {\rm{x}}\end{aligned}\)

Step 2: Result.

Therefore, the curve is\({\rm{y = }}\sqrt {\rm{3}} {\rm{x}}\).
