The original coordinates of the point in polor coordinates are
A. X’=r cos (Ф +ϴ) and Y’=r cos (Ф +ϴ)
B. X’=r cos (Ф +ϴ) and Y’=r sin (Ф +ϴ)
C. X’=r cos (Ф -ϴ) and Y’=r cos (Ф -ϴ)
D. X’=r cos (Ф +ϴ) and Y’=r sin (Ф -ϴ)
Answer:A
The original coordinates of the point in polor coordinates are
A. X’=r cos (Ф +ϴ) and Y’=r cos (Ф +ϴ) B. X’=r cos (Ф +ϴ) and Y’=r sin (Ф +ϴ) C. X’=r cos (Ф -ϴ) and Y’=r cos (Ф -ϴ) D. X’=r cos (Ф +ϴ) and Y’=r sin (Ф -ϴ)
Explanation: The original coordinates of the point in polor coordinates are X’=r cos (Ф +ϴ) and Y’=r sin (Ф +ϴ).
