Question

Evaluate the modulus of the complex number

Answer 1

modulus is just the length of the point from the origin

Answer 2

\[\left| (5/10)-(1/10)i \right|\]

Answer 3

a + bi can be thought of as coordinate points (a,b)

the modulus being the disance of (a,b) from (0,0) = sqrt(a^2+b^2)

Answer 4

\[|z|=\frac{\sqrt{5^2+1^2}}{10}\]if i see that right

Answer 5

isn't it slightly different in the complex plane, since you generally graph polar in the complex plane? It's been too long since i did modulus questions to remember, lol.

Answer 6

nah, its completely analogolous

Answer 7

or whatever that word is lol
