ordered pair negative 3 divided by 2 comma 3 divided by 2
ordered pair 3 square root 3 divided by 2 comma negative 3 divided by 2
ordered pair negative 3 divided by 2 comma 3 square root 3 divided by 2
ordered pair 3 divided by 2 comma negative 3 divided by 2
The correct answer is C. ordered pair negative 3 divided by 2 comma 3 square root 3 divided by 2
(r,θ) = (x,y) x = r * cosθ y = r * sinθ Since your θ is 5π3, set your calculator to radians before taking the sine and cosine.
(3 cos 5π / 3, 3 sin 5π / 3) (3* 1 / 2, 3 * - sqrt(3) / 2) (3 / 2, −3 sqrt (3) / 2) if r = -3, then x is negative, y is positive.
Here are the following choices: A. ordered pair negative 3 divided by 2 comma 3 divided by 2 B. ordered pair 3 square root 3 divided by 2 comma negative 3 divided by 2 C. ordered pair negative 3 divided by 2 comma 3 square root 3 divided by 2 D. ordered pair 3 divided by 2 comma negative 3 divided by 2
