Complex Numbers Polar Form

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

For the number -1+5i the argument measured in degrees would be

• between 0 and 90°

• between 0 and -90°

• between 90° and 180°

• between -90° and -180°

For the number 2-3i the argument measured in degrees would be

• between 0 and 90°

• between 0 and -90°

• between 90° and 180°

• between -90° and -180°

For the number -7-8i the argument measured in degrees would be

• between 0 and 90°

• between 0 and -90°

• between 90° and 180°

• between -90° and -180°

For the number 3+4i the argument measured in degrees would be

• between 0 and 90°

• between 0 and -90°

• between 90° and 180°

• between -90° and -180°
