This applet can be used to approximate a definite integral numerically by the trapezoid rule, Simpson's rule, the left or right endpoint rules, or the midpoint rule. The user enters the function, the endpoints, and the number of intervals. The function is checked for correct syntax, and the user can choose a graphical display of the approximation. The applet is accompanied by a help menu. This applet can be used to approximate the zeros of a function by Newton's method. The user enters the function, an initial value, and a stopping criterion. The function is checked for correct syntax, and the user can enter an interval for a graphical display. The applet is accompanied by a help menu.
This applet can be used to approximate the zeros of a function by using the Intermediate-Value Theorem to identify sign changes. The user enters the function, the number of subintervals for each subsequent subdivision, and a stopping criterion. The function is checked for correct syntax, and the applet is accompanied by a help menu. This Applet can be used to fit linear, exponential, power, and logarithmic models to a set of data. The user can supply the data as y-values only or xy-pairs. The data can be typed in or pasted from other sources. The program computes the required coefficients and the correlation coefficient (based on linearizing the data). The program can also generate random data. The applet is accompanied by a help menu. |
