Question
The polar coordinates of a certain point are (r = 3.15 cm, 0 = 262°).
(a) Find its Cartesian coordinates x and y.
x = |-0.438
cm
= |-0.312
Your response is off by a multiple of ten. cm
(b) Find the polar coordinates of the points with Cartesian coordinates (-x, y).
= |1.41
Your response differs from the correct answer by more than 10%. Double check your calculations. cm
= |-45
Your response differs from the correct answer by more than 10%. Double check your calculations.
(c) Find the polar coordinates of the points with Cartesian coordinates (-2x, -2y).
= 2.83
Your response differs from the correct answer by more than 10%. Double check your calculations. cm
225
The response you submitted has the wrong sign.
%3D
(d) Find the polar coordinates of the points with Cartesian coordinates (3x, -3y).
= 4,24
Your response differs from the correct answer by more than 10%. Double check your calculations. cm
