Answer
Rectangular equation:
$x^2 - y = 0$
Graph:
Work Step by Step
**Remember:(I) $r^2 = x^2 + y^2$, (II) $tan(θ) = \frac{y}{x}$, (III) $rcos(θ) = x$, (IV) $rsin(θ) = y$
$r = sec(θ)tan(θ)$
$r = \frac{1}{cos(θ)}tan(θ)$
Multiplying both sides by "cos(θ)":
$rcos(θ) = tan(θ)$
Using (II) and (III):
$x = \frac{y}{x}$
Multiplying both sides by "x":
$x^2 = y$
$x^2 - y = 0$
