Chapter 9: Q 50. (page 731)

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

x=4

Short Answer

Expert verified

The required equation isr=4sec胃.

Step by step solution

01

Step 1. Given information.

The given equation in rectangular coordinates is:

x=4

02

Step 2. Find the equation in rectangular coordinates. 

x=4

As we know that x=rcos胃 in polar coordinates, then substitute the value of x,

rcos胃=4

Divide both sides by cos胃,

rcos胃cos胃=4cos胃r=4sec胃

Therefore, the equation in polar coordinates isr=4sec胃.
