Short Answer

In Problems 39-54,the poplar coordinates of a point are given.Find rectangular coordinates of each point.

(6,150°)

The rectangular coordinates corresponding to the polar coordinates (6,150°)are(-33,3)

See the step by step solution

Step by Step Solution

Step 1. Given information

The given poplar coordinates of a point (6,150°)

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=rcosθand y=rsinθ .
Substitute 6 for r and 150° for θ in to get the value of x .

x=rcosθ =6.cos(150°) =6.-32 =-33

Step 3. Find the value of y.

y=rsinθ =6.sin150° =6.12 =3

Therefore, the rectangular coordinates corresponding to the polar coordinates (6,150°)are (-33,3)
