Problem 2 . ( Module 8 ) 5 points Consider the function g ( t ) = x 2 e - x 2 . Determine
Problem Module points
Consider the function
Determine true derivative of computed analytically in the point using MATLAB
program and symbolic operations.
Determine numerical derivative in the point and using selfdeveloped
MATLAB programs for various difference formulae:
a Twopoint backward difference formula.
b Twopoint forward difference formula.
c Twopoint central difference formula.
d Taylor series based difference formula.
Find the percentage relative error in each case.
Note: Matlab program ModExamplem can be used; however, it is work only for Forward
difference, and needs to be bar aapted to the other formulas.
Put your answer in this field: Represent the result with decimal places.
