• With polar coordinates, θ can be calculated and displayed within a range of
–180°< θ < 180° (radians and grads have same range).
• Be sure to specify Comp for Mode in the SET UP screen.
Example Operation
Calculate r and θ ° when x = 14 and y = 20.7 u3(SET UP)cccc1(Deg)i
K6(g)3(ANGL)g(Pol()

Calculate x and y when r = 25 and θ = 56° u3(SET UP)cccc1(Deg)i
K6(g)3(ANGL)h(Rec()

1 24.989 → 24.98979792 (r)
2 55.928 → 55.92839019 (θ)
1 13.979 → 13.97982259 (x)
2 20.725 → 20.72593931 (y)
