Question

Use a graphing utility to find the rectangular coordinates of the point given in polar coordinates. Round your results to two decimal places.

Answer 1

Step 1 :

The point in polar co-ordinates is .

1). Draw a coordinate plane.

2). Plot the polar point .

Graph the point in rectangle coordinates.

3). Observe the above graph, the x  - coordinate of the point lies between .

4). It is appears to be .

5). Observe the above graph, the y  - coordinate of the point lies between .

6). It is appears to be .

7). Thus, the rectangle coordinates for the polar point is .

Solution :

The rectangle coordinates for the polar point is .
