[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: \[ \int_{x_1}^{x_n} y(x) dx \approx \frac{1}{2} \sum_{k=1}^{n1} (x_{k+1}x_{k})(y_{k+1}+y_{k}) \] Many thanks Marcio
