# Math Help - Do I have this right?

1. ## Do I have this right?

I'm looking to find the trig polar form of -4+4i

I came up with 4 times the sq root of 2 times (cos 7pi/4 + i sin 7pi/4)
am I close or way off? Thanks in advance for the help!

Because $-4+4i$ is in the second quadrant the argument is $\frac{3\pi}{4}$.
