Graphing Calculator Workshop

  1. Welcome & Intro
  2. Graphing Calculators
    1. Which models - differences?
      1. 83 basic
      2. 84 -- apps... periodic table
      3. 89 CAS / Pretty Print
        1. Show an indefinite integral
        2. show a definite integral
        3. do a derivative
        4. solve (2x^2 - 3e^x=0)
        5. factor 6x^3 + 31x^2 - 7x - 60
    2. Which classes?
    3. Which tests can they be used on?
      1. ACT CAAP - 83 & 84, not 89 (because of CAS)
      2. AP Calculus & Statistics- any graphing calculator without QWERTY keyboard
      3. SAT math
    4. Virtual TI
  3. Keys & operation
    1. setting contrast 2nd up/down
    2. home screen (2nd quit)
    3. show manual page with key groups
    4. 2nd, alpha, negative
    5. Entry on left, answer on right
    6. editing entries
      1. arrows
      2. arrows & 2nd
      3. del
      4. clear
      5. insert (2nd ins)
    7. Mode
      1. normal
      2. float
      3. degree
      4. real/(a + bi) ...
        1. do the sqrt(-9) in both modes.
        2. do ln(-1) in both modes
      5. (left items are defaults)
    8. Operations
      1. +, -, *, /
      2. powers
      3. roots
      4. inverse
      5. implied multiplication (2pi)
    9. using functions
      1. logs
      2. trig
      3. inverse log/trig
      4. Math menu
        1. Math...roots, fraction, decimal
        2. Number...abs, lcd, gcf
        3. complex...conjugate, convert polar
        4. probability...nCr, nPr, !, randInt
      5. catalog
        1. all functions built in to the calculator
        2. press a letter to get there (no alpha needed)
        3. 89 advantage: catalog explains the syntax, too
      6. Order of Operations - basic algebraic
      7. variables ... use STO to keep values
    10. Solver
      1. 0=a^2+b^2-c^2
    11. Algebra A uses
      1. order of operations exercises
      2. lcd/gcf
      3. statistics (mean)
      4. Square Root
      5. pythagorean theorem
  1. Graphing
    1. one function
      1. first thing: stat plot (2nd y=) 4: plots off
      2. y= button
      3. "on" to stop a malfunctioning graph
      4. enter a function (x^2 -4x +7)
        1. edit
        2. line style (inequalities)
        3. show/hide
      5. zoom
        1. std used often
        2. square to see equal-ratioed axes
        3. fit sometimes works and sometimes not
      6. window to adjust
      7. trace
        1. with arrows
        2. with values
        3. enter re-centers
      8. zoom in or out
      9. calc
        1. zeros
        2. min
        3. max
        4. (calculus - derivative & integral)
      10. Family of curves
        1. {1,2,3,4}sin(x)
        2. sin({1,2,3}x)
      11. table
        1. table
        2. tbl set
        3. scroll with arrows
    2. multiple functions
      1. intercepts
    3. can also graph parametric & polar plots
    4. Algebra 1 & 2 uses:
      1. graphing functions, looking at parameters
      2. finding zeros
      3. finding intercepts
      4. finding max & min
