Find the rectangular coordinates of the point with the polar coordinates (1, 1 divided by 2 pi).
(0, -1)
(1, 0)
(0, 1)
(-1, 0)

  (0, 1)

Step-by-step explanation:

The angle (1/2)π radians is equivalent to 90°. Since angles are measured counterclockwise from the +x axis, an angle of 90° (or π/2 radians) is in the direction of the +y axis.

Your polar coordinates of 1∠(π/2) specify a point 1 unit up from the origin on the y-axis. The coordinates of that point are (x, y) = (0, 1).

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400
