1.12.3 Numerical integration (A-level only)

Card 1 of 23

Numerical integration estimates a definite integral using [     ] rather than exact algebraic integration.

A

If f′′(x)>0f''(x)>0f′′(x)>0 throughout an interval, the trapezium rule gives an overestimate. If f′′(x)<0\boxed{f''(x)<0}f′′(x)<0​ throughout, it gives an underestimate.

B

If f′′(x)>0\boxed{f''(x)>0}f′′(x)>0​ throughout an interval, the trapezium rule gives an overestimate. If f′′(x)<0f''(x)<0f′′(x)<0 throughout, it gives an underestimate.

C

Numerical integration estimates a definite integral using numerical function values rather than exact algebraic integration.

D

f′′(x)f''(x)f′′(x) changes sign within the interval.
