Expert Solution
Step 1

we have to determine which of the following statements are true:

  •  For all polar coordinates, (r,θ) and (r,−θ) describe the same location.
  •  For all polar coordinates, (r,θ) and (−r,−θ) describe the same location.
  •  For all polar coordinates, (r,θ) and (r,θ+2π) describe the same location.
  •  For all polar coordinates, (r,θ) and (−r,θ) describe the same location.
  •  For all polar coordinates, (−r,θ+π) and (−r,θ−π) describe the same location.
  •  For all polar coordinates, (r,θ) and (−r,θ−π) describe the same location.
