Examples: Use nDeriv to find the derivative of f(x) = x2 + 1 at x = -1. The derivative of f(x) = x3 is 3x2 so f’(2) = 12. Check the result on the calculator. It is important to recognize exact values and approximate values. It is most helpful to use nDeriv with functions that are difficult to …

(In this case, the slopes of the secant lines do get closer and closer to the slope of the tangent line. But that’s not what limit means and not the best description of how the slopes of secant and tangent lines are related in general.) II.6. The derivative of the function y = f(x) at x = 3 is defined by the equation f′(3) = .

However, when secant method converges, it will typically converge faster than the bisection method. However, since the derivative is approximated as given by Equation (2), it typically converges slower than the Newton-Raphson method. The secant method …

Derivative of sec(x) (Secant) | Detailed Lesson
If x = 1, then f (1) = 1 and the slope of the line tangent to this graph at x = 1 is 3. You evaluate the derivative at the x value to get this number, and it will change as x changes. In the “Big Picture”: For an itsy bitsy step off of 1 to the right, the y value will go up 3 times the size of that step.

if , then the derivative also fails to exist as . The following examples show four cases where the derivative fails to exist. At a corner. For example , where the derivative on both sides of differ (Figure 4). At a cusp. For example , where the slopes of the secant lines approach on the right and on the left (Figure 5).
