With integration, one of the major concepts of calculus. Differentiation is the derivative or rate of change of a function with respect to the independent variable.
There are two ways to define the derivative of a function f at a given number a:
(see attached photo)
Choose the ANSWERS that correctly and strongly justify why we take h → 0 in equation (B).
We always have a = 0, so the two equations agree with h = b.
h is the run (denominator) of the slope for the secant line that passes through (a, f(a)) and (a + h, f(a + h)), and we want this run to approach zero to get the slope of the tangent line.
h is equal to zero.
Comparing equations (A) and (B), we see that so taking h → 0 is equivalent to b → a.
Since f'(a) is the limit of a difference quotient (ratio of the difference in outputs to the difference in inputs), h = final input value - initial value
Use central difference to show that the fourth derivative of f(x) is:
The temperature of a chemical reaction oscilates between a low of 25 C and a high of 120 C. The temperature is at its lowest point at time t=0, and reaches its
maximum point over a two and a hailf hour period. It then takes the same amount of time to return back to its initial temperature. Let y = H) denote the temperature of the
reaction f hours after the reaction begins.
