To calculate: The polar coordinates of a point provided that rectangular coordinates are
Answer to Problem 49E
The polar coordinates of the point are
Explanation of Solution
Given information:
The rectangular coordinates of the point are
Formula used:
To convert the rectangular coordinates
Calculation:
Consider the rectangular coordinates of the point are
Recall that to convert the rectangular coordinates
Here,
Therefore, value of r is,
And, value of
Here value of
Observe that the rectangular coordinates lie in fourth quadrant. So, the value of
Thus,
Hence, the polar coordinates of the point are
