This puzzle combines two of my favorite activities -- Silly Definitions and a Right Angle Puzzle.

Determine the answer to each "calculus definition" below.

Then write the word in the 12 x 12 matrix using the following rules:
(1) Each word makes one right angle turn somewhere along its length.
          But it is your task to determine where each word makes this turn and in which direction.
(2) As a guide, the starting direction of each answer word (i.e., the direction of the word before
          the right-angle turn) is indicated by the letter given after the clue number.   Words
          can go north, south, east, or west to start with.
(3) Of additional help is the fact that each letter in the correctly completed grid appears in exactly
          one word.
