3.8.4 Numerical Methods (A-level only)

Card 1 of 22

For nnn equal strips across [a,b][a,b][a,b], the strip width is [...]\text{[...]}[...].

A

When f′′(x)=0f''(x)=0f′′(x)=0 throughout, so the graph is a straight line.

B

For equal strips, the trapezium estimate and rectangle sums satisfy T=L+U2\boxed{T=\frac{L+U}{2}}T=2L+U​​.

C

For nnn equal strips across [a,b][a,b][a,b], the strip width is h=b−an\boxed{h=\frac{b-a}{n}}h=nb−a​​.

D

At xix_ixi​, the corresponding ordinate is yi=f(xi)\boxed{y_i=f(x_i)}yi​=f(xi​)​.
