and scroll down to "argument".

Why did they call the magnitude, or the length of the line or vector from the origin to the point (x,y) the "Modulus" of the complex number x + yi? The Mathematician Jean-Robert Argand (17681822) first use the term "modulus".
`
My answer to both: They had to call them something! LOL. I sort of like "argument" and "modulus" because both the word AnGle and the word "ArGument" both have an "A" first and a "G" third. You can remember "Modulus" because "Magnitude" also starts with an M.
