What is the argument of -5i? I have been stuck on this for a while!
argument of -5i ?
I haven't ever heard of such a concept in math -:(
argument i think is the same as the angle, yes?

wow a celebrity! hello!!
you can see what the angle is directly from the picture you have lots of choices because it is not unique
I still really don't understand it. Could you explain it to me please in more depth?
you need to find the angle between the initial ray and the terminal ray that is find this angle: |dw:1401679079632:dw|
Okay...I still don't know how to exactly get the answer though. It is confusing for me.
you know that is a right angle?|dw:1401680681402:dw|
Is the argument 3pi/2 then?
the argument is simply the measurement of the angle between the initial ray in the terminating one you could say 270 degrees or even -90 degrees And of course you can use radians to describe the measurement of the angle
