... Multiplication by w is an isometry if the distance between wz1 and wz2 is equal to the distance between z1 and z2 for any complex numbers z1 and z2 . |wz1 − wz2 | = |w(z1 − z2 )| = |w| |z1 − z2 |, so this equals |z1 − z2 | if and only if |w| = 1, or in other words a2 + b2 = 1. Note this is also the ...

Parts of an Expression
... • Term- Mathematical expressions that contain constant (number) and variables (letters). A number that is by itself is called constant and a number that is attached to a variable is called a coefficient. Terms are separated by addition or subtraction. Terms are joined together by multiplication. ...
