    FRACTIONS On most scientific calculators and also the Casio graphics calculator there is a special key for entering fractions. No such key exists for the TI-83, so we use a different method. Texas Instruments TI-83 To enter common fractions, we enter the fraction as a division.
  • Page 4: Basic Functions

    For example, to enter 25 we type 25 Note that there are special keys which allow us to quickly evaluate squares. Numbers can be squared on both TI-83 and Casio using the special key For example, to enter 25 we type 25...
  • Page 5 To enter square roots on either calculator we need to use a secondary function (see the Secondary Function and Alpha Keys Texas Instruments TI-83 The TI-83 uses a secondary function key 36 we press To enter The end bracket is used to tell the calculator we have finished entering terms under the square root sign.
  • Page 6: Inverse Trigonometric Functions

    GRAPHICS CALCULATOR INSTRUCTIONS INVERSE TRIGONOMETRIC FUNCTIONS To enter inverse trigonometric functions, you will need to use a secondary function (see the Secondary Function and Alpha Keys Texas Instruments TI-83 ¡1 ¡1 ¡1 The inverse trigonometric functions sin , cos and tan are the secondary functions of respectively.
  • Page 7: C Secondary Function And Alpha Keys

    . The answer is 2 £ 10 SECONDARY FUNCTION AND ALPHA KEYS Texas Instruments TI-83 The secondary function of each key is displayed in yellow above the key. It is accessed by pressing the key, followed by the key corresponding to the desired secondary function.
  • Page 8 Values can be stored into the variable letters A, B, ..., Z using either calculator. Storing a value in memory is useful if you need that value multiple times. Texas Instruments TI-83 Suppose we wish to store the number 15:4829 for use in a number of calculations.
  • Page 9 If you wish to view the answer in fractional form, press RECALLING PREVIOUS EXPRESSIONS Texas Instruments TI-83 The ENTRY function recalls previously evaluated expressions, and is used by pressing ENTER This function is useful if you wish to repeat a calculation with a minor change, or if you have made an error in typing.
  • Page 10: Creating A List

    Lists are used for a number of purposes on the calculator. They enable us to enter sets of numbers, and we use them to generate number sequences using algebraic rules. CREATING A LIST Texas Instruments TI-83 1 to take you to the list editor screen. Press...
  • Page 11 Casio models without the List function can do this by pressing (LIST) OPTN (List) 1 NUMBER SEQUENCES Texas Instruments TI-83 You can create a sequence of numbers defined by a certain rule using the seq command. I to enter This command is accessed by pressing STAT the OPS section of the List menu, then selecting 5:seq.

  • Page 14 It is often useful to find the points of intersection of two graphs, for instance, when you are trying to solve simultaneous equations. Texas Instruments TI-83 12 ¡ x We can solve y = 11 ¡ 3x and y = simultane- ously by finding the point of intersection of these two lines.
  • Page 15 In the special case when you wish to solve an equation of the form f (x) = 0, this can be done by graphing y = f (x) and then finding when this graph cuts the x-axis. Texas Instruments TI-83 ¡ 3x...
