A screen with showing settings will appear. FUNC should be the only item highlighted. Here are some options to consider for determining the graphing window. The standard graphing window may work well for some graphs, but often will not work well for application problems. For application problems, the situation in the problem may provide clues to selecting an appropriate window; some guessing and trial and error may be involved. Read the problem to see if the wording gives clues about an appropriate window such as giving values for points that are on the line or curve or stating some x or y values of interest in the problem.
After looking at the graph, adjust the window as needed if it does not show an appropriate view. Find and graph the cost function. Use Xscl and Yscl to specify the desired interval for the tick marks shown on each axis. Determining a window: The problem refers to a time period of 10 years, so Xmax should be at least Ymax should be at least as large as the amount Vijay will have at the end of 10 years, but in this case should be higher because we decided to include x values up to We can calculate 1.
It usually takes a few tries, but it gets easier with more experience. Y Zoom In or Zoom Out repeatedly, if needed. The calculator will show the graph in the current graphing window with the cursor located at the center.
If the intersection of the two functions does not show in the window, adjust the graphing window to see the intersection point. Adjust the window manually or Zoom Out, as per instructions above. If the intersection of the two functions is visible in the window, continue below:. The screen shows both functions. A point on the graph of equation Y1 is highlighted showing the prompt First curve? Next, a point on the graph of equation Y2 is highlighted showing the prompt Second curve?
The prompt Guess? Use the right and left arrow keys to move the cursor along the line until it is near the point of intersection; press ENTER. The screen will display the Matrix menu. Use the right arrow key twice to select the EDIT menu. The shape of the matrix adjusts on the screen to show the requested number of rows and columns. Check that the shape matches the desired matrix; if it does not, then return to the top row and adjust the dimensions. If the matrix is too large to fit the screen, use the arrow keys to scroll right or down to see the remaining rows and columns.
The cursor scrolls through the matrix by moving across each row from left to right and then down to the next row. Using the arrow keys to move the cursor instead of pressing ENTER may result in a value not being stored in the calculator memory. After entering all data, proofread the matrix. Use the arrow keys to move the cursor to the proper position if any entries need correction.
Matrices are indicated by a capital letter between square brackets, such as [A] or [C]. This is a single symbol and must be selected from the Matrix menu any time a matrix is needed. If we type three characters [ followed by A followed by ] the calculator will not interpret the three symbol sequence [A] as a matrix and will not call up the matrix.
To call a matrix back to the screen to view or use in a calculation, at any time after editing, use the MATRIX menu to enter the matrix name. This selects a matrix name to use only. It does not permit editing the matrix. To edit the matrix, arrow right over to the EDIT menu as described earlier.
Transposing a matrix means switching the rows and columns. Columns become rows and rows become columns. The calculator will display the transpose obtained by interchanging rows and columns.
Use the matrix names menu to insert the matrix names. What the calculator does: Multiplies each entry in matrix A by 3. Stores result in Matrix C. What the calculator does: Adds entries in matrices A and B. Stores the result in matrix C. Example: Several operations in the same step: 4A - 3B. What the calculator does: Performs scalar multiplication and subtraction to find matrix 4A - 3B.
What the calculator does: Uses matrix multiplication to multiply matrix A by matrix B to find the matrix product AB. The screen shows the command such as [A] - 1. The commands below explain the row operations that are built into the calculator.
Be careful to enter the information into the command exactly as explained below. If information is put in the wrong order, the calculator will do exactly what it is told to do and give an incorrect answer for what was intended; the calculator follows commands but cannot read read minds to know what was intended if the information is not entered correctly. I guess I'm a little confused still; Can you maybe provide some examples of inputs and expected CE Python Programming.
I am not experiencing the error from there but I did fix it with whats in there but I'm just I don't know this for sure, but I'm wondering if the error is coming from changing Str4 while the Here is the latest version.
