Think about how errors accumulate.
3Question 3.
What is the formula for Local Truncation Error in Euler’s method?
Show hintHide hint
Recollect the basic formula applied in Euler's method.
4Question 4.
True or False: Global truncation error is accumulated from local truncation errors.
Show hintHide hint
Think about how each step's error contributes to the total.
Question 5.
Using Euler's method, calculate the local and global truncation errors for $h = 0.1$ over the interval [0, 1] for the differential equation $dy/dx = y$ with $y(0)=1$ .
Show hintHide hint
Look for patterns in how errors accumulate across the defined interval.
Question 6.
Explain the trade-off between accuracy and computational resources when choosing step sizes in truncation errors.
Show hintHide hint
Think about both sides of the accuracy versus computational cost argument.
