Dear participants to the list,
this is my problem: I want to find zeros of an arbitrary function.
With uniroot (package stats) it is possible to find (numerically) a root of
the function,
but I do not know how I can find at the same time the zeros
in a determined interval (if this function must
Dear participants to the list,
this is my problem: I want to obtain an expression that represents the second
derivative of one function.
With deriv3 (package stats) it is possible to evaluate the second
derivative, but I do not know how I can get the (analytical) expression of this
derivative.
