<P> Greek letters are used in mathematics , science , engineering , and other areas where mathematical notation is used as symbols for constants , special functions , and also conventionally for variables representing certain quantities . In these contexts , the capital letters and the small letters represent distinct and unrelated entities . Those Greek letters which have the same form as Latin letters are rarely used : capital A , B , E , Z , H , I , K , M , N , O , P , T , Y , X . Small ι , ο and υ are also rarely used , since they closely resemble the Latin letters i , o and u . Sometimes font variants of Greek letters are used as distinct symbols in mathematics , in particular for ε / ε and π / π . The archaic letter digamma ( Ϝ / ϝ / ϛ ) is sometimes used . </P>
