Answer:
True , -5i = 5*(0 - i) = 5*( cos 3π/2 + i*sin 3π/2) = 5*(cos 270 + i*sin 270)
Step-by-step explanation:
5*( cos 3π/2 radians + i*sin 3π/2 radians) = 5*(cos 270 degrees + i*sin 270 degrees)

<span>P = (6,31°) is already a polar coordinate.
In the notation (r, </span>α) if you make r negative, it points in the opposite direction. If you add 180° to α you compensate for that.
Therefore (6,31°) = (-6,31°+180°) = (-6, 211°)
However, it is more usual to keep r positive.
how do you want it to be simplified? my fraction, decimal or percent? because if you’re asking if the fraction can be simplified any smaller it can’t but if your asking for decimal or percent let me know and i could try to help you out
