Find the graph represented by polar coordinates (ρ - 2) (θ - π) = 0 (ρ≥ 0)

Find the graph represented by polar coordinates (ρ - 2) (θ - π) = 0 (ρ≥ 0)

(ρ - 2) (θ - π) = 0 (ρ≥ 0) gives ρ - 2 = 0 or θ - π = 0
The equation ρ = 2 represents a circle with the pole as the center and radius of 2
The equation θ = π (ρ ≥ 0) denotes the opposite extension of the polar axis
Therefore, (ρ - 2) (θ - π) = 0 (ρ ≥ 0) denotes a circle and a ray

What graph is the polar equation r = 2 + 2cos θ? How did it come from

A point on the number axis that represents an integer is called an integral point. The unit length of a certain number axis is 1 cm. If you draw a random number on the number axis
How many integral points are covered by a line segment AB with a length of 2011 cm?

If the numbers corresponding to two points a and B on the number axis are √ 3 + 2 √ 2 and 2 √ 2 - √ 3 respectively, then the length of line AB is?

2 radical 3
That's right. He's wrong

If two points a and B represent the sum of numbers on the number axis, then the length of line AB is______ .

If two points a and B represent numbers a and B respectively on the number axis, then the length of line AB is ∣ B-A ∣

On the number axis, the numbers represented by points a and B are - 2 and 3 respectively, then the length of line AB is

3-(-2)=5
A: the length of segment AB is 5

A unit length on the number axis represents 1cm, and the number of point a on the number axis is 2. If line AB = 5cm, then point B will be replaced
