Vinny Graphics Sample Math Problems: Problem #1 Make an X,Y table from test data. Given: Test data: X Y 4.79 98.312 5.34 145.23 6.93 201.67 8.86 376.81 Create an X,Y table with X going from 4 to 9 in steps of 0.5. and round Y to 1 place. Solution: 1- FILE | OPEN | TEXT FILE | Math_Sam.txt (This opens this file in the Vinny Graphics text editor) 2- PREFER | enter Max Data Index of 30. Click OK. (Sets length of new data files equal to 30 rows) 3- FILE | NEW DATA. WINDOW | TITLE VERT. (Opens a new data set and arranges windows) 4- Drag mouse over above test data make sure to include both columns but do not include X Y titles. (Selects above data for the following copy) 5- EDIT | COPY. (Copies selected data to Windows clipboard) 6- Click on data set #1 cell [X1, 1] (Makes data set #1 active and selects cell [X1, 1]) 7- EDIT | PASTE. (Pastes data from Windows clipboard starting in selected cell) 8- Right click data set #1 and select Y Fit. (Opens local pop up menu and then opens regression dialog) 9- Click 2nd Order Polynomial. (Does a 2nd Order Polynomial regression of the X,Y data in set #1) 10- Click OK. (Closes regression dialog and completes action) 11- FILE | NEW DATA. (Opens new data set #2) 12- MATH | FILL CELLS and enter the following values: Start Index : 1 Stop Index : 11 Start Value : 4 Step Value : .5 (This sets up user defined sequence) 13- Click the Operate button (This fills data set #2 X values between index 1 and 11 with the user defined sequence.) 14- Click OK. (Closes the Fill Cells dialog) 15- Click on data set #2 cell [X2, 1] then Drag mouse over X2 column data from 4 to 9. (Selects X2 data for the following copy) 16- EDIT | COPY. (Copies selected data to Windows clipboard) 17- Click on data set #1 title and then cell [X1, 5]. (Selects data set #1 cell [X1, 5] for the following paste) 18- EDIT | PASTE. (Pastes data from Windows clipboard into empty X cells and then automatically fills in a corresponding curve fit value for Y) 19- Drag mouse over Y1 column data from 94.7... to 389.5... (Selects new Y1 data for the following math operation) 20- MATH | OPERATE on CELLS and select Operation Round(Cell) then enter 1 in the Constant K edit box. (Selects Rounds off operation sets up one decimal digit Note: The total, average and sigma are displayed for the selected group of cells) 21- Click the Operate button (This performs round off of selected cells to one decimal place. Note: The Y1 Fit is automatically cleared any time the data changes.) 22- Click OK. (Closes the Operate on Cells dialog) The data table should look like this: 4 94.7 4.5 102.9 5 115.8 5.5 133.5 6 155.9 6.5 183 7 214.8 7.5 251.4 8 292.7 8.5 338.7 9 389.5 A graph of this data can be viewed by: 21- FILE | OPEN | GRAPH FILE | Math_Sam.gra. Click OK. Click Yes. (Closes data set #1 & #2 and opens Math Sample graph file.)
