QUESTION 1 Transform the polar equation to an equation in re

QUESTION 1 Transform the polar equation to an equation in rectangular coordinates. Then identify and graph the equation. 5 43 223 horizontal line 4 units above the pole .3 -4

Solution

Polar to rectangular conversion

(r , theta)

x = r cos(theta)

y= r sin(theta)

so given equation in polar form

r sin(theta) = 4

y = 4

Horizontal line 4 unit above the pole

A is right answer
