Chapter 9: Q. 53 (page 568)

In Problems 39–54, the polar coordinates of a point are given. Find the rectangular coordinates of each point.
$(6.3, 3.8)$

Short Answer

Expert verified

The rectangular coordinates is $(- 4.98, - 3.85)$ .

Step by step solution

Step 1. Given Information

We are given polar coordinates of a point,

$(6.3, 3.8)$

The rectangular coordinates are given by $x = r \cos θ$ and

$y = r \sin θ$

Step 2. Finding the rectangular coordinates

The rectangular coordinates is given by,

$x = r \cos θ = 6.3 \cdot \cos (3.8) = 6.3 (- 0.7909) = - 4.98$

Similarly,

$y = r \sin θ = 6.3 \times \sin (3.8) = 6.3 \times - 0.6118 = - 3.85$

So, the rectangular coordinates is $(- 4.98, - 3.85)$ .
