Question

calculate the(area) trapezoidal rule for f(x)=√sin(x) on [0,π] for n=2

Answer 1

Approximate the area under the curve of f(x)=√sin(x) on [0,π] for n=2:
Have you used the trapezoidal rule before? If so, would you please type it out here, identifying (b-a)/n?

Answer 2

If the interval in question is [0,π], n=2, how many y values are we to compute, and what are they?
