HP35s and numerical differentiation
What would be the simplest way of estimating a slope of tangent to function/expression (say, already stored in equation library) for a specified variable at a specified point?
I imagine I could write a programme that would use, say, twopoint secant formula (or some higher precision formulas), but how would I parse a function from an equation library to it? Is there a simpler way?
