$(x, y) = (2, 3)$ $color(indigo)((x,y) = (2,3))$

![ www.nabla.hr )

$(r, θ (= (3.6, {56.31}^{\circ})$ $(r, theta( = (3.6, 56.31^@)$

$x = r cos h η = 3.6 \cdot cos 56.31 \approx 2$ $x = r cos heta = 3.6 * cos 56.31 ~~ 2$

$y = r sin θ = 3.6 \cdot sin 56.31 \approx 3$ $y = r sin theta = 3.6 * sin 56.31 ~~ 3$
