Numerical Approximation
1. Increasing the value of the variable width will:
2. Which method divides the interval into equal segments and uses the function value at the midpoint of each segment to estimate area?
3. For which type of function does the rectangle approximation method give the exact area under the curve?
4. True or False: Numerical approximation methods can be used to estimate the area under any curve, regardless of whether the function is integrable analytically.
