Cards In This Deck

• $$\begin{gathered} \text{What is the formula for the strip width }h\text{ when using the Trapezium Rule to estimate }{\int }_a^{b}y \\ ,dx\text{ with }n\text{ strips?} \end{gathered}$$
  $h=\frac{b-a}{n}$
• $$\begin{gathered} \text{True or False?} \\ \text{If using the Trapezium Rule with }n=4\text{ strips, you need to calculate exactly 4 values of }y\text{.} \end{gathered}$$
  $$\begin{gathered} \text{❌ False} \\ \text{✅ Correct: You need }n+1\text{ values of }y\text{.} \end{gathered}$$
• $\text{How do you decide if the Trapezium Rule will produce an underestimate or an overestimate?}$
  $\text{Look at the concavity (shape) of the curve.}$
