Expert Solution
Step 1

Note: Since you have posted a question that is time-consuming in computation and lengthy, we have solved the question only for forward and backward difference schemes. Kindly, post the question again mentioning the question to be solved for the central difference scheme and to calculate f''(10).

 

Given the table,

To calculate f'(6) using forward and backward difference schemes.

 

Let us compute the difference table,

Step 2

Forward difference formula for the 1st derivative,

dydxx=x0=1hy0+2p-12!2y0+3p2-6p+23!3y0+4p3-18p2+22p-64!4y0+5p4-40p3+105p2-100p+245!5y0+···where, p=x-x0h

In our case, 

x=6, x0=5, h=2p=6-52=0.5And,y0=0.318994042y0=-0.070045033y0=0.021446594y0=-0.006187965y0=0.00035336Now, 2p-12!=03p2-6p+23!=-0.0416666674p3-18p2+22p-64!=0.0416666675p4-40p3+105p2-100p+245!=-0.036979167Substituting, we getdydxx=6=0.158914767
