It includes xFact and yFact settings for 2-dimension and zFact for 3-dimensional graphs. 6.6.2 F3: Trace Trace allows you to use the cursor to trace your graph using the left/right arrow keys. It displays the coordinates of the cursor’s location.

  • Page 31: F5: Math

    CHAPTER 6. GRAPHING EQUATIONS/FUNCTIONS 6.6.3 F5: Math 1: Value Value will allow you to calculate a y-value when you enter in an x-value and it will visually move the cursor to this (x, y) coordinate. In some ways this is similar to what you can do with the Trace feature.
  • Page 32 CHAPTER 6. GRAPHING EQUATIONS/FUNCTIONS 2: Zero Zero will identify the zeros (a.k.a. the x-coordinate of an x-intercept) of your function. To use this command, the calculator will ask for a lower bound and upper bound, which tells the calculator which x-values to look between. If more than one zero is found, the least (left-most) zero will be identified.
  • Page 33 CHAPTER 6. GRAPHING EQUATIONS/FUNCTIONS 3: Minimum Minimum will find the minimum y-value between your identified lower bound and upper bound and it will visually move the cursor to this (x, y) coordinate. Example: Find the minimum y-value between the x-values of 0 and 2. Press to use the Minimum command.
  • Page 34 CHAPTER 6. GRAPHING EQUATIONS/FUNCTIONS 4: Maximum Maximum is the counter-part for the Minimum command. Maximum will find the maximum y-value between your identified lower bound and upper bound and it will visually move the cursor to this (x, y) coordinate. Example: Find the maximum y-value between the x-values of -3 and 0.
  • Page 35 CHAPTER 6. GRAPHING EQUATIONS/FUNCTIONS 5: Intersection Intersection will allow you to determine where two different functions intersect, between your identified lower bound and upper bound and it will visually move the cursor to this (x, y) coor- dinate. In addition to identifying the lower bound and upper bound, you will need to identify which two functions you want to consider.

    CHAPTER 7. USING THE TABLE The Table Settings Press to enter the TBLSET screen. There are four potential settings that you can adjust. The bottom setting, Independent, is the most important. Independent: Auto or Ask If this is set to Auto , your table will be automatically generated using the other three settings. If this is set to Ask , you will need to enter in each x-value one at a time for the table to have any information.
