For nnn equal strips across [a,b][a,b][a,b], the strip width is [...]\text{[...]}[...].
When f′′(x)=0f''(x)=0f′′(x)=0 throughout, so the graph is a straight line.
For equal strips, the trapezium estimate and rectangle sums satisfy T=L+U2\boxed{T=\frac{L+U}{2}}T=2L+U.
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.
At xix_ixi, the corresponding ordinate is yi=f(xi)\boxed{y_i=f(x_i)}yi=f(xi).
Flashcards for WJEC A Level Maths 3.8.4 Numerical Methods (A-level only), covering the key formulae, methods and definitions you need to recall for AS Unit 1, AS Unit 2, A2 Unit 3 and A2 Unit 4. 22 cards, matched to the WJEC A Level Maths (1300QS) specification. Recall questions account for roughly 50% of marks at A Level Maths, so these target the marks you can secure before the paper starts.
