I'm trying to write a program to find values for arctan of x by using taylor series. An initial value of x is given by the user and then it should print solutions from arctan(x) to arctan(1) in increments of x+0.1. It prints correctly but gives incorrect values after the initial x. I'm new to c and need some way to 'reset' the functions f1 and f2 for each increment of x (I think...)
Here's the code
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <iostream>
#include <fstream>
using namespace std;
int main() {
/* Define the beginning of the program and each variable. Also opens a text file to be written to */
FILE *f = fopen("arctan.txt", "w");

Write a function that computes the Taylor series expansion of ex using the following formula, where x is the exponent, and n is the number of discrete trials to run:
ππ₯=1+π₯+π₯2+π₯3+π₯4+β―+π₯π =βπ π₯π 2! 3! 4! π! π=0 π!
NOTE: This formula will NOT work if you calculate the numerator and denominator separately and then add the division result. You must use your knowledge of algebra to make sure youβre not calculating the entire exponent and factorial, but rather their factors per loop iteration.
Input prompt
Enter the values for x and n:
Output Prompt
Taylor series estimation is XXXX.XXXX
This is what I have so far for the function:
void getTaylor() {
double estimation
cout << "Enter the values for x and n:" << endl;
cin >> x >> n;
cout << "Taylor series estimation is" <<
}
I now need to create the loop so that I can enter in for my function.
Write a C program with a separate function which calculates the sine function from the first principles according to the formula below. The code should find the sine value in 5 stages and then final answer
formula below :
sin(x) = x βx3/3!+x5/5!βx7/7!+x9/9!
I have done the code and it just gives me a final sine wave
it should find a error then plus one so on till it gets the answer

I want to write an algorithm to find the kth term of a series given by the following recursive formula:
a_0=1 and a_(k+1)=a_k+1/k!
My code (part of it responsible for calculating the value of a series) does not want to compile:
Code:
float series(int n)
{
float F0 = 1;
float F;
unsigned int i;
if (n == 0)
return(1);
[Code]...
thus my question is why it does not want to work properly and what should i change (for certain factorial function is OK)?
Example input: 2 4 6 -1 7 3 -2 1
Output: 3 3 (longest series of even is 3, longest series of positive is 3)

int even(int x) {
return x % 2 == 0;
}
int positive(int x) {
return x>0;

My question is how to write this code if the prototype of function is:

I am trying to write a menu program that will be broken down into a series of calls to function for each of the menu items. Two of the menu items will be simple programs which I wrote.
I want two of the functions to run one of the two programs I am trying to include as items in the menu.
So far I am only familiar with variables, loops, if statements, and I just learned how to write functions.
The problem I am have is that I don't quite understand how to write a function that will run one of the two programs. Also I am having a hard time writing the program in away that would allow the user to select the menu items.
This program does everything i want except for one major problem and one small one.
1. The program keeps taking my last entered number and counting it as max and min
2. When I go to end with 0 it adsd the enter number prompt then returns.

Write a program that approximates the value of Ο using the Leibniz series and compares the Leibniz series approximation against the known value of Ο and two other common approximations of Ο (22/7 and 355/113). The program must prompt the user for the desired number of terms (n) to use in the approximation (as an integer) and calculate the approximate value of Ο to the given number of terms. The program must display each approximation of Ο and display the difference between each approximation.
I understand how to prompt for the number, what I don't even get how to start is to use it to approximate the value of pie in that given number. Also how to tell the difference between each approximation...
I can't seem to get the math portion right. It is supposed to approximate pi using (sigma,i=-1 to infinity)(-1)^(i+1)(4/(2i-1))=4(terms of pi). And what I have does some math but it is incorrect because I get a negative value for pi and one that is entirely too large at that. The precision is also to be at 20 decimal places. I also need it to end immediately after if I get an invalid input, but I can't seem to get it to end after trying a few different things it will say that it is an invalid number, but will continue to run the math loop. I also need the final cout to print all the terms that is multiplied by 4.

cout<<"This program approximates pi using an n-term series expansion. "<<endl;
[code]....
in code my prompt said :
(computing Ξ (PI) ) You can approximate (PI) value by using the following
series:
Ξ = 4( 1 - 1/3 + 1/5 - 1/7 + 1/9 - 1/11 + ... - 1/(2i -1) + 1/(2i + 1)
Write a method that calculate value of Ο by using the above series, using
the following header:
public static double pi()
assume i = 1000000
ok so I have been testing it but I really did get any far :
for ( double i = 1; i< 1000000; i+=2) {
// with these I try to increment the value of i to get to the series. I did these after and test it and the output is all wrong and I know it
sum = (1/((2*i)+1));
sum = sum + (1/((2*i)-1));
sum ++;
double pi = 4*(sum);
// I know is wrong I but I can't figure it out what to do.

I'm attempting to print a series of text from this loop, but for some reason all I am getting is the sum total and the number 1, like this
1 5175.11
When I want to get it for each iteration of the loop. I've cycled over this and compared it to my other loops I've used and I'm lost as to why this isn't working. I also tried using a do while but that didn't work as well.
for (double total1 = 0; total1 < goal; total1 + save_amt) {
total2 = ((factor - one) * save_amt);
total3 = (total2 / fr_interest);
total1 = total1 + total3;
months_dis = (months_dis + one);
cout << months_dis << " " << total1 << endl;

I'm having trouble, I want the inner loop to display the lowest and highest score. If I assign initial values for the high and low score, it won't always work (because if no/ all scores are above/ below my initial values...)
But without assigning initial values for highscore and lowscore, One of them will always be undefined during the first runthrough.
