Average velocity is given by. Instantaneous velocity is given by. The slope of the tangent line to the graph of a function at a point is called the derivative of the function at that point. The formal definition of derivative is given below. Formal Definition of Derivative. The derivative of a function f at x = a is. Illustrating Secant Line Convergence. For functions that have a tangent line, if the point (a, f(a)) on the curve is fixed, as h approaches zero the second point (a+h, f(a+h)) approaches the fixed point and the corresponding secant lines converge to the tangent line at that point. The procedure outlined below will find the value of the derivative of the function f(x) = 2x - x. Find the slopes of several secant lines and use them to estimate the slope of the tangent line at x = 0. Then take the limit of the slopes of the secant lines to find the derivative. The graph below illustrates f(x) = 2x - x. Finding Slopes of Secant Lines. The first step in the procedure outlined above is to find the slopes of secant lines that will be used to estimate the derivative. To find the slopes you need to enter the function f(x) = 2x - x. Y= editor. The slope of the secant line through the points (0. We are interested in values of h that are small so that the two points are close together. The resulting secant line will approximate the tangent line. You may evaluate the difference quotient for h = 0. TI- 8. 3 by using a two- part command. The first part of the command will store 0. The two commands will be combined together with the colon symbol. The slope of the secant line containing (0. Using Smaller Values of h. As the point (0. 5 + h, f(0. To evaluate the difference quotient for smaller values of h, change the value of H in the last expression on the Home screen from 0. The slope of the corresponding secant line is 0. Evaluate the difference quotient with h = 0. The slopes of the secant lines are 0. Predict the derivative at (0. Click here for the answer. Left- hand Difference Quotients. In the procedure above, right- hand difference quotients were used. Left- hand difference quotients may be found by letting h be a negative number. Left- hand difference quotients. The slopes of the corresponding secant lines are 1. With the fixed point (0. Finding a Derivative at a Point. As stated earlier, the derivative at x = 0. Before this limit can be evaluated, the expression. Recall that the function of interest is f(x) = 2x - x. Therefore. and the derivative of f(x) = 2x - x. Using the Numeric Derivative Command. You can also approximate the derivative of the function at a point by using the numeric derivative command n. Deriv(, which is found in the Math menu. The syntax for finding a derivative at a point is n. Deriv(expression,variable,value). Drawing the Tangent Line. Because the point on the curve and the derivative at that point are both known, an equation for the tangent line may be found by using the. If the slope of the tangent line at (0. Graph f(x) = 2x - x. Set Y1 = 2. X - X2. Set Y2 = (X- 0. 5) + 0. Graph both the function and the tangent line in a [- 1, 3, 1] x [- 1, 2, 1] window. The line appears to be tangent to the curve at x = 0. Calculus Using the TI- 8.
