What are the rectangular coordinates of the point with polar coordinates $\left(r,\theta\right)=\left(-10,\frac{\pi}{6}\right)$(r,θ)=(−10,π6)?
Consider the point with rectangular coordinates $\left(0,-5\right)$(0,−5). Represent this number in modulus argument form, with $0^\circ\le\theta<360^\circ$0°≤θ<360° and $r>0$r>0.
Consider the point with rectangular coordinates $\left(-5,0\right)$(−5,0). Represent this number in modulus argument form, with $0^\circ\le\theta<360^\circ$0°≤θ<360° and $r>0$r>0.
