(3)Place the stylus on the screen and hold it there 301 uTo draw a line tangent to a graphExample: To draw a line tangent to the graph y = x2 – x – 2 when x (1)In line y1 of the Graph Editor window, input and save y = x2 – x – (2)Tap $to graph the function (3)Tap [Analysis], [Sketch], and then [Tangent] (4)Press This displays a dialog box for inputting the point of tangency (6)Press E uTo draw a line that is normal to a graph 302 uTo graph the inverse of a functionExample: To graph y = x2 – x – 2 and then overlay it with x = y2 – y – (3)Tap [Analysis], [Sketch], and then [Inverse] uTo draw a circleExample: To draw a circle with a center point located at (1, 1) and a radius of While the Graph window is active, tap [Analysis], [Sketch], and then [Circle] •This display “Circle” on the Graph window (2)Press This displays a dialog box for specifying the center point coordinates (3)Enter value for x, y, and r, and then tap [OK] 303 uTo draw a vertical or horizontal lineExample: To draw a vertical line at x This displays a dialog box for specifying the •This closes the dialog box and draws the vertical line at x uTo clear figures inserted using the Sketch menu• This redraws the graph
