Question

represent 8 in rectangular form​

Answer 1

Step-by-step explanation:

The answer is x2+(y−4)2=42

Explanation:

To convert from polar coordinates (r,θ) to cartesian coordinates (x,y), we use the following equations

x=rcosθ

y=rsinθ

x2+y2=r2

Here, we have

r=8sinθ

r=8⋅yr

r2=8y

x2+y2=8y

x2+y2−8y=0

Completing the squares

x2+y2−8y+16=16

x2+(y−4)2=42

This is the equation of a circle, center (0,4) and radius =4

graph{x^2+(y-4)^2=16 [-13.88, 14.6, -2.85, 11.39]}
