Convert to Polar Coordinates (-2,0)

Problem

(−2,0)

Solution

1. Identify the Cartesian coordinates (x,y) where x=−2 and y=0

2. Calculate the radius r using the formula r=√(,x^2+y^2)

r=√(,(−2)^2+0^2)

r=√(,4)

r=2

3. Determine the angle θ by identifying the position of the point on the coordinate plane. Since the point (−2,0) lies on the negative x-axis, the angle is π radians or 180^∘

θ=π

4. Express the result in the polar coordinate form (r,θ)

Final Answer

(−2,0)⇒(2,π)
