The illustration on the display will help you determine where to enter the known values. Note: if you need to change the angle neasure mode, press MODES, change the mode, and then press to return to the aplet. 4. Press . The solver calculates the values of the unknown variables and displays. As the illustration at the right shows, the length of the unknown side in our example is 3.2296. (The other two angles have also been calculated.) Note: if two sides and an adjacent acute angle are entered and there are two solutions, only one will be displayed initially. In this case, an menu key is displayed (as in this example). You press to display the second solution, and again to return to the first solution. No solution with given data If you are using the general input form and you enter more than 3 values, the values might not be consistent, that is, no triangle could possibly have all the values you specified. In these cases, No sol with given data appears on the screen. The situation is similar if you are using the simpler input form (for a right-angled triangle) and you enter more than two values. 9-3
