When a complex number z is written in its polar form, z=r(cos(theta)+isin(theta) , the nonnegative number r is called the "_____," or modulus, of z.

I'm confused since the only term I know for r would be the modulus.

Thanks(:

Pre-calc actually haha

norm

zzr0ck3r · Answer

or I guess complex norm is the term used.

anonymous · Answer

It would be complex norm in fact then? Not just norm?

zzr0ck3r · Answer

"the distance from the origin"

zzr0ck3r · Answer

complex norm is safer, but this is just terminology stuff, so both are right

zzr0ck3r · Answer

there may be other names....

Alright haha, they never taught it in the lesson yet it showed up. I only knew modulus. Thankyou(:

zzr0ck3r · Answer

no one ever says it.

zzr0ck3r · Answer

but the modulus is the distance from the origin, and that is sometimes called the norm. this is misleading as there are infinite different norms one can impose on a set...

It was actually the magnitude.....

anonymous · Answer

which makes sense but I only think about magnitude in vectors..

It's alright haha! Thankyou anyway(:
