Chapter 9: Q 49. (page 731)

In Exercises 48鈥�55 convert the equations given in rectangular coordinates to equations in polar coordinates.

y=0

Short Answer

Expert verified

The required equation is胃=0.

Step by step solution

01

Step 1. Given information.

The given equation in rectangular coordinates is:

y=0

02

Step 2. Find the equation in rectangular coordinates. 

y=0

As we know that y=rsin胃 in polar coordinates, then substitute the value of y,

y=rsin胃rsin胃=0sin胃=0rsin胃=0胃=0sin0=0

Therefore, the equation in polar coordinates is胃=0.
