What is the modulus of a complex number?

• List of numerical values created when dealing with irrational and rational numbers

• the distance between the point of origin (0,0) and the point (a,b) on the complex plane

• area of an angle on a complex plane from r=θ

• number chosen when completing scale evaluation of angle x and y

Find the modulus of the complex number. Also state what quadrant the point would land in.

• √10, Quadrant 2

• √10, Quadrant 3

• 2, Quadrant 2

• 3, Quadrant 3

When a complex number is drawn on the complex plane. The distance from the origin is the value of

• the argument

• The modulus

• The real co-efficient

• The imaginary co-efficient

Find the magnitude of z = - 4 + 2i

Let w=-√3/2 + 1/2 i calculate the modulus and argument.

• 3, 120^o
