Given this CFG

Determine the the sets FIRST() where is any of the right sides of the productions.

For each element z belonging to the set FIRST(BaA) give a derivation starting from BaA of a string w with first symbol z (or in case FIRST(BaA), a derivation of from BaA).

For each element z belonging to the set FOLLOW(B) give a derivation starting from S of a string w where z occurs directly after B.

S + BaA A | | b | cB |
