Polar Form: (3.6,-56.3)

Polar format: $(r, theta)$

$r=sqrt(x^2+y^2$

$theta=tan^-1(y/x)$

Apply both formulas when going from Cartesian -> Polar

$sqrt(2^2+(-3)^2) = sqrt(13) = 3.6$

$theta = tan^-1 ((-3)/2) ~~ -"0.98 radians"$

Thus our answer of:

Polar format of $(2,-3)$ Cartesian:

$(3.6, 0.98)$
