Input the desired parametrized formulas for x and y into the X 1T= and Y 1T= fields, respectively. If necessary, change the Angle mode to the units ( RADIAN or DEGREE) you want to use for t. Press MODE, use the arrow keys to scroll to PAR and press ENTER.
Then press ENTER to evaluate the integral. Input the lower limit of integration and press ▲, input the upper limit of integration and press ►, input the integrand function and press ►, and then input X. Press MATH, then scroll to 9:fnInt( and press ENTER. The calculator will display the root of the equation that occurs within the specified interval for x. Press ◄ as many times as desired to move to a position within the specified interval for x that is close to the desired root. Press ENTER to set the upper bound chosen in Step 9. This is the upper bound of the interval for x. Press ► as many times as desired to move to any position to the right of the desired root. Press ENTER to set the lower bound chosen in Step 7. This is the lower bound of the interval for x. Press ◄ as many times as desired to move to any position to the left of the desired root, which is an x-intercept on the graph. Press 2nd, then TRACE to open the CALCULATE menu, and scroll down to 2:zero. Input the function, with x as the variable. The calculator will generate corresponding values of the function in the Y 1 column.įinding Roots of an Equation of the Form f( x)=0 Input values in the X column that approach the value that the independent variable approaches in the limit. Press 2nd, then GRAPH to display the table. Press WINDOW to input the window settings. Input the function whose limit you wish to predict. This may or may not lead to a correct guess for the limit, depending on the viewing window specified for each graph. Use caution when trying to determine the value of a limit by inspecting graphs of a function. Press GRAPH to display the graph in the new viewing window. Press WINDOW to input new window settings. Be sure the interval of x-values for the viewing window includes the value that the independent variable approaches in the limit. Input the function whose limit you wish to visualize. Press ENTER to calculate the slope a and y-intercept b of the best-fitting line for the data. Ylist: field and press 2nd, then 2 to input Press STAT, then ► to open the STAT CALC menu.
Input the values of the independent variable in column L 1, and input the corresponding values of the dependent variable in column L 2. Press STAT to open the STAT EDIT menu and select 1:Edit…. To improve the appearance of the graph, press MODE, use the arrow keys to scroll to DOT, and press ENTER. Press ENTER as many times as desired to zoom in on graph. Press ZOOM to open the ZOOM menu, and scroll down to 2:Zoom In. Input the function or functions that you wish to graph. If necessary, repeat Step 3 to adjust the window settings to get a better view of the graph and then repeat Step 4 to display the graph. Break up any compound inequality into two separate inequalities, and input each separate inequality enclosed in parentheses. In the Y 2= and Y 3= fields, repeat Steps 2, 3, and 4 to input the second and third pieces of the piecewise defined function and their domains. In the Y 1= field, input a left parenthesis, the first function, a right parenthesis, a division bar, a left parenthesis, and then X. Input the three pieces of the piecewise defined function separately by entering the functions enclosed in parentheses as numerators and the domains of the functions enclosed in parentheses as denominators, as follows. Graphing a Piecewise Defined Function with Three Pieces In the Y 2= field, repeat Steps 2, 3, and 4 to input the second piece of the piecewise defined function and its domain.
Press ENTER, input the rest of the inequality to express the domain of the first function, and then input a right parenthesis. Scroll down to the desired inequality symbol for the domain of the first function. Press 2nd, then MATH to open the TEST menu. Input the two pieces of the piecewise defined function separately by entering the functions enclosed in parentheses as numerators and the domains of the functions enclosed in parentheses as denominators, as follows. Graphing a Piecewise Defined Function with Two Pieces To evaluate the function at a given value of x while the graph is displayed, press TRACE and then input the given value of x.
