TIB: Functions
I'm new to the TI-89 and I'm trying to write a function that will compute
the numerical approximation of an integral using the Left Sums methods.
The function will be defined as:
LeftS( fn, a, b, n )
where fn is a function in terms of x, a is the lower limit, b is the
upper limit, and n is the number of intervals.
I want to know how I can evaluate fn at specific x values, however I
couldn't find a function that does that in the manual.
Thanks,
J.W.
