PAPER 2 TOPIC 4

P2-4.1 Polar Notation

Polar coordinates: $(r, \theta)$

$r$ = distance from origin, $\theta$ = angle from positive x-axis

P2-4.2 Conversion Formulas

Conversion	Formulas
Polar → Cartesian	$x = r\cos\theta$, $y = r\sin\theta$
Cartesian → Polar	$r = \sqrt{x^2 + y^2}$, $\tan\theta = \frac{y}{x}$
