The function to be differentiated or integral will typically be in one of the three forms:
A simple continuous function; a polynomial, an exponential, a trigonometric function. be evaluate analytically using calculus…
A complicated continuous function that is difficult or impossible to differentiate or integrate directly. analytical solutions are often impractical, and sometimes impossible… approximate method must be employed
A tabulated function where values of x and f (x) are given at a number of discrete points, as if often the case with experimental or field data. approximate method must be employed…
