Coding a loop of polynomial with a given X to find f(x) in Java
So I have trouble coding a loop of a polynomial with a given x to find f(x) in java.
To put it simply, for example, I have an array of f(x) = C[0]*x^n + C[1]*x^(n-1).......C[n]n, how would I code a loop to find f(x) with the user's input of…

recursive segmentation fault
So I wrote a header that uses recursion to compute several mathematical functions. Including the cosine function and exponential function( e^x). Now the cosine functions works just fine but e^x produces a segmentation fault even though both use the…

Computing cubic polynomial
I need a procedure that returns the value of a cubic polynomial, ie :
f(x) = x3 + ax2 + bx + c
I should be able to do this with a procedure that takes three arguments and Newton-Raphson's method but I am at a loss on how.
(define f (cubic a b c)…

Calculating polynomal function
Considering a sequence of integers, how can I find the polynomial function that models it? (i.e generates the first item for x=1, second items for x=2, etc)
For example, let us consider this sequence: 1, 683, 44287, 838861. How do I find that the…

Optimal solution to find the coefficients from an unknown polynomial function
Suppose I have a polynomial f(x) where all the coefficients a(i) are integers in the form of a function f, implement a function find_polynomial that takes f and returns the coefficients a(i) as a list of the form:
[a(0),a[1]....a[n]] (n<=15)
where…

is it possible to write a program that can find zeros of a certain function?
In Gauss-legendre integration we need to find zeros of the legendre function but i can't find a way to write code that enable me to do that?
I understand there are list of "xi"s out there by which this function equals to zero but can we write…

I need some help on polynomials
How would I create a polynomial function using an array? Basically I want to display the polynomial (ex. x^2 + 3x + 5). Then, I want to show what the highest polynomial degree is. For example, x^2 + 3x + 5 = 2 (highest degree).
