[WP 34s] Trapezoidal approximation of area under curve
Hello all,

Is it possible to have access to data keyed into the calc using the $$\sum +$$ for other procedures other than stat functions? If so, I am planning on creating a program that would take advantage of that so it would be possible to easily calculate the area under a curve defined by data, as shown below:

$\int_{x_1}^{x_n} y(x) dx \approx \frac{1}{2} \sum_{k=1}^{n-1} (x_{k+1}-x_{k})(y_{k+1}+y_{k})$

Many thanks

Marcio
