Derivative or Integral Of A Function
(a) The derivative of the function f(x) at x = c is defined as f′(x)=lim f(c+h)− f(c)/h
One way to attempt an estimate of f ′(c) is to choose a positive value of h that is as close to zero as Visual
Basic allows, and then to evaluate the quotient. Unfortunately, round-off errors can be very large. A better method is to evaluate the formula f (c + h)− f (c)/h
for smaller and smaller values of h, until the difference between successive approximations falls below a predetermined level.
Write a program to calculate the derivative of a polynomial of degree n expressed as
anxn +an−1xn−1 +...a1x+a0
where the coefficients an, a n-1,...,a1 , and, a0 are real numbers, n is a nonnegative integer, and an is not equal to zero. The program should accept as input the degree and coefficients of the polynomial along with a real number, c, and calculate the slope of the function at c.
Hi, Nice to know your requirement. I am an excel vba, vb6 expert and have delivered fourteen excel vba projects in the past seventy days.
Willing to take up your project. Thank you, Regards.
Hi,
I can write the program you requested. I just have a note to make. If you want to find a derivative of a polynomial, there's no need to use the definition of the limit. This can be done analytically, unless, of course, you just want to test how the convergence process works.
Sincerely,
Serge

Hello
This is a simple one project. The calculations are easy. Given the degree of the polynomial, an excel area will prompt the user to enter all the values of coefficients and finally the number c The result will be displayed in a new cell. If one of the values is not a numeric(text, or blank) the program will prompt the user to correct this value.
Thank you
Nikos
