6 USING THE TI-Nspire CAS AND TI-Nspire HANDHELDS Determining the Points of Intersection of Two Functions 1. Enter both relations into the data entry line of the Graphs and Geometry application. Ich habe eine TI nSpire CAS mit Touchpad und in Mathe die Augaben teilweise Wurzelziehen, wert unter eine wurzel bringen z.B (3a²b mal Wurzel aus 5b in eine wurzel bringen) und den Nennner wurzelfrei machen Kann ich das im TI rechnen wenn ja wie danke. For example, enter y 5 5x 1 4 in f1(x), and then press. Enter y 5 22x 1 18 in f2(x), and then press. Adjust the window settings until the point(s) of intersection is (are) displayed. You can do this by changing the window settings or by picking up the graph and moving it. Move the cursor to an empty area in the window. Hold the click key down until a closed fist appears. Use the arrow keys to move the graph until you see the intersection point(s). Press and scroll to 6: Points & Lines 3: Intersection Point(s), and then press. When the line blinks, press to select the line. Repeat this process to select the second line. As you move the cursor near the second line, a point will appear at the intersection. To make the point permanent and to know its coordinates, press. Note: If there is more than one point of intersection, all the points of intersection that are visible in the window will appear.

Graph the function and determine the lower zero. In the Graphs and Geometry application, enter the function y 5 x 2 1 x 2 5. Press and scroll to 6: Analyze Graph 1: Zero to determine the lower zero of the function.
Move the cursor over the coordinate label for the zero.Ĭhange the number of digits displayed for the zero. It will change to a hand icon with text next to it. Use the or key to change the number in the Custom Precision box to 4, then press. Change the number of digits displayed for all values.
