$color(cyan)("Polar Form " (r, theta) = (sqrt 325, 356.82^@)$

![ www.nabla.hr )

$"Given : " x = 1, y = -18$

$r = sqrt(x^2 + y^2) = sqrt(-1^2 + 18^2) = sqrt 325$

$theta = arctan (y/x) = arctan (-1/18) = 356.82^@, " IV Quadrant"$

$color(cyan)("Polar Form " (r, theta) = (sqrt 325, 356.82^@)$

What is the polar form of (1-,18)(1-,18)?
