    ANSWER

    Rectangular to polar coordinate, (x,y)⟶(r,θ)

    radius,r can be found by using , r=

    x

    2

    +y

    2

    r=

    (−1)

    2

    +(−1)

    2

    =

    2

    θ can be found using the reference angle:tanθ=

    x

    y

    tanθ=

    −1

    −1

    ⟹tanθ=1⟹θ=tan

    −1

    1=

    θ=

    4

    −3π

    As the point (-1-1) lies at Quadrant

    iii)i.e, θ=

    −3π

    From (r,θ)=(
