Question

Can you help me? it's about numerical numbers question.

i want to second derivative like this first derivative solution.

And with analytical solution.

 

First Derivative
Error
f(x+1) -f(x-1)
f'(x) =
O(k)
2h
-f(x;+2) + 8ƒ (x+1) – 8f(x;-1) + f (x;-2)
12h
f'(x) =
O(k')
Second Derivative
f(x;+1) – 2f(x) +f(x-1)
f"(x) =
O(h?)
h?
-f (x42) + 16f(x;+1) – 30ƒ(x) + 16f (x--1) – f(x;-2)
12h
f"(x) =
O(h")
Third Derivative
f(*2) – 2f(x,) + 2f(x;-1) – f (x-2)
f" (x) =
O(h)
2h
-f(x3) + 8f(x,+2) - 13f(x;1) + 13f(x_-1) – 8f(x,-2) + f(x,_)
f"(x,) =
O(h")
8h
Fourth Derivative
f(x+2) – 4f(x;+1) + 6f(x) – 4f(x¡-1) + f(x;-2)
f" (x) =
fm(z) = f3) + 12f(x;+2) + 39f(x,) + 56f(x,) – 39f(x,-,) + 12f(x,_2) + f(x )
6h
O(h*)
In the above table, the formulations to calculate different order derivatives of a function are given by using the
central difference method.
For the functionf (x) = !n (x), obtain the first, second, third and fourth order derivatives of this function by using
the above methods for the neighborhood step h = 0.01 at the point x = 4.0.
Soru çözüm formatı oluşturması adına birinci türevin elde edilme yöntemi aşağıda verilmiştir
f (x) = In (x) f(4.0) = ? f "(4.0) = ? f "(4.0)= ? f "(4.0) = ?
h = 0.01 için x, = 4.00 x = 4.01 x-1 = 3.99 x-2 = 4.02 x-2 = 3.98
İki nokta için birinci türev
f (4.0) =
f (4.01)- f (3.99) 1.3888 –1.3838
2(0.01)
= 0.25
0.02
Dört nokta için birinci türev
-f (4.02)+ 8f (4.01) – 8 f (3.99)+ ƒ (3.98) (-1.3913)+8(1.3888)– 8(1.3838)+1.3813
f'(4.0) =
= 0.25
12 (0.01)
12(0.01)
Analitik çözüm
f (x) = In (x) → f(x)=1/x → f'(4.0)= 0.25
Using the solution format given above, obtain the second, third and fourth order derivatives of the
function f (x) = In (x). Compare the results you get with the numerical solution with the derivatives
you get with the analytical solution for the relevant function.
