How do you use a trapezoidal riemann sum?
The trapezoidal sum is the average of the left and right Riemann sums for the same partition of
I'm not sure what you are asking.
The trapezoidal sum is one thing and the Riemann sum is a rectangular sum.
They are related as stated above.

To use a trapezoidal Riemann sum, follow these steps:
- Divide the interval of integration into subintervals of equal width.
- Calculate the function values at the endpoints of each subinterval.
- Use the trapezoidal rule formula to find the area of each trapezoid formed by adjacent function values.
- Sum up the areas of all trapezoids to approximate the integral.
The formula for the trapezoidal rule is:
[ \text{Area} = \frac{h}{2} \left[ f(x_0) + 2f(x_1) + 2f(x_2) + \ldots + 2f(x_{n-1}) + f(x_n) \right] ]
Where:
- ( h ) is the width of each subinterval (( h = \frac{b - a}{n} ), where ( a ) and ( b ) are the limits of integration, and ( n ) is the number of subintervals).
- ( x_0, x_1, x_2, \ldots, x_n ) are the endpoints of the subintervals.
- ( f(x_0), f(x_1), f(x_2), \ldots, f(x_n) ) are the function values at the endpoints.
Finally, sum up all the individual trapezoidal areas to get the approximation of the integral.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
