Chapter 9: Q. 44 (page 567)

In Problems 39-54,the poplar coordinates of a point are given.Find rectangular coordinates of each point.
$(5, 300 °)$

Short Answer

Expert verified

The rectangular coordinates corresponding to the polar coordinates $(5, 300 °)$ are $(\frac{5}{2}, - \frac{5 \sqrt{3}}{2})$

Step by step solution

Step 1. Given information

The given poplar coordinates of a point $(5, 300 °)$

Step 2. Finding the value of x.

For a point P on the terminal side of $θ$ and having polar coordinates $(r, θ)$ , the corresponding rectangular coordinates are given by $x = r \cos θ$ and $y = r \sin θ$ .
Substitute 5 for r and $300 °$ for $θ$ in to get the value of x.

$x = r \cos θ = 5 \cos (300) = \frac{5}{2}$

Step 3. Finding the value of y.

Substitute $300 °$ for $θ$ and 5 for $r$ in $y = r \sin θ$ to get the value of y.

$y = r \sin θ = 5 \sin (300 °) = - \frac{5 \sqrt{3}}{2}$

Therefore, the rectangular coordinates corresponding to the polar coordinates $(5, 300 °)$ are $(\frac{5}{2}, - \frac{5 \sqrt{3}}{2})$
