Use the Trapezoidal Rule to approximate the area bounded by the graph of
f(x) = cos3(x)
between x = 0 and x = 3 and the x-axis. Use N = 6
- At the main menu, either enter 3
or use the arrow keys to move to 3. Integral
- At the prompt, Interval of integration, type in 0
for a and 3
- At the prompt for function, type (cos(x))^3
- At the prompt, Method 1 type T
- At the prompt, Number of intervals, type 6
- Press to draw the graph.
- At this point, you will see the graph.
