numerical methods Flashcards
1
Q
when to use euler’s methods/ euler’s improved
A
differential equation
2
Q
condition for simpson’s rule
A
even number of strips or odd number of ordinates
3
Q
how many ordinates and strips
calc h
A
n+1 ordinates
n strips
h = Δlimits/n
4
Q
table for numerical methods
A
ordinate ,x ,y
5
Q
mid-ordinate x-ordinates and how many
A
n ordinates (discard n+1/2) :
1/2 3/2 …. n-1/2
x1/2 = x0 +1/2 h
then add h for each subsequent ordinate
6
Q
convex/ concave shape
A
concave = n
convex = u
7
Q
under/overestimate mid-ordinate
A
concave is over
convex is under ( shape is u)
