WebYou could perhaps take a finite difference approach. Consider the second derivative as a difference quotient in terms of the first derivative: $f''(x)= \frac{f'(x+h)-f'(x)}{h}$ Substitute …
WebThe derivative f ′ (x) of a function f(x) at the point x = a is defined as: f ′ (a) = lim x → af(x) − f(a) x − a The derivative at x = a is the slope at this point. In finite difference approximations of this slope, we can use values of the function in the neighborhood of the point x = a to achieve the goal. http://www.learningaboutelectronics.com/Articles/Diode-approximations.php
