I. How to store equations

• 1. Press Program Button PRGM
• 2. Move cursor to NEW and select Create New
• select ALPHA to name folder in which you will
  store equations, hit enter when you are finished
• 3. Type in an equation, hit enter to store
• 4. To exit, type 2ND MODE (Quit)

II. How to use the table

• 1. After having graphed the equation, to use
  table hit 2ND GRAPH (Table)
• 2. The table may be used to find the zeros and
  matching X-Y coordinates
• 3. To find the zeros, scroll down or up X-column
  to look for a zero if there is no zero look for
  a change from to -, or to .
• if you cannot find a zero, change the table
  settings by 2ND WINDOW (TBLSET)
• 4. To raise or lower the first X-coordinate, type
  a new number under TblStart
• 5. To increase or decrease the increments between
  X-coordinates (ex. By 0.5 instead of
• type a new number under Tbl
• 6. To see modified table, hit 2ND GRAPH.
• 7. Continue modifying table if necessary

III. Calc section

• Finding indefinite integrals
• Enter the equations that you want to find the
  integrals of
• Press 2nd TRACE (Calc)
• Once in the Calc section press 7 and then enter
• Select the two points that the integral is
  between by moving the curser to one point and
  pressing enter and then moving the curser to the
  other point and pressing enter

IV. Math section tricks

• This section of your calculator contains buttons
  which are not on the calculator.
• Frac (Fractions) This button converts decimals
  to fractions.
• Dec (decimals) This button converts fractions to
  decimals.
• Allows you to cube an equation
• Allows you to cube root an equaiton
• Allows you to find a variable root.

V. Graphing tricks

• Shading
• Once in the Y format, move the cursor two clicks
  to the left until the diagonal line is
  highlighted.
• Toggle the line by pressing ENTER until a small
  triangle appears facing either up or down (for
  shading above or below the line)
• Press GRAPH to see the shaded region
