Answer:
(1, -1)
Step-by-step explanation:
To convert polar to rectangular coordinates, use these identities:
Here we were given the point [tex](\sqrt{2},-\frac{\pi}{4})[/tex] which is our (r, Ф) point
We can now plug these values into our x and y equations to convert to rectangular and find our (x, y) point
So our (x, y) point is (1, -1)
