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:
šš„=1+š„+š„2+š„3+š„4+āÆ+š„š =āš š„š 2! 3! 4! š! š=0 š!
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 youāre 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 āx3/3!+x5/5!āx7/7!+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

These are images of what it should look like and the image of a the formula ....
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");
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.
I am making a program to run Fibonacci series. I have created 2 array.
1)- 1st array holds only 0, 1 2)- 2nd array holds other values eg: 1, 2, 3, 5..........etc
I am using while loop to get the febonacci series and storing it in a 2nd array called int[] numbers.
After getting value using while loop, I am joing both the arrays using int[] final = arr.Concat(number).ToArray();
At last, I have used foreach loop to add the febonacci series into the listbox.
The problem I have is that, I cannot able to concat both the arrays. I tried to assign number array at the top of the while loop. so that number variable will be accessible outside the while loop. But I am getting a error.

Write a program that approximates the value of Ļ using the Leibniz series and compares the Leibniz series approximation against the known value of Ļ and two other common approximations of Ļ (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 Ļ to the given number of terms. The program must display each approximation of Ļ 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.
[code]#include <iostream> #include <cmath> #include <iomanip> using namespace std; int main() { int nterm, numerator; double sum = 0.0; const int upperBound = nterm * 2; cout<<"This program approximates pi using an n-term series expansion. "<<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.
#include <iostream> using namespace std; const int AGRADE = 90; const int BGRADE = 80; const int CGRADE = 70; const int DGRADE = 60; int main() {
[code]....
how do i set this up so it stores a low and high score, and then compares those to each next number in the series?
I need to write a program that not only calculates the minimum and maximum, but also calculates the average and the difference between the largest and the smallest.
How to remake the code that i`ve written to have : a recursive function to evaluate the first n terms in series specified y= 1 - x + x^2/2 - x^3/6 + x^4/24 +....+(-1)^n x^n/n!
And this is my code:
#include <iostream> using namespace std; double power(int n, double x) { double d =1; for (int i = 1 ; i<=n ; i++)
#include <iostream> #include <iomanip> using namespace std; #define SIZE 20 void Fibonacci( int ); int main( ) { cout << "How many numbers are in the Fibonacci Series? ";
I was asked to create a C++ program that allows a user to take a test with series of different questions, and also retake the test if they choose to. I have been able to do that. But the other condition is to display the highest and lowest scores (highest and lowest correct answers) the user got, and in which test they got that score. For example, if the user takes the test 3 times, in which test did they get the highest score, and in which did they get the lowest score.
This is how far I went with the program. The code below only let the user take the test as much as they want, and tell them how many times they took it, and the last score they had. My idea is this, if I can make a variable store each test score, then I can compare them. But since there is no definite number of tests to be taken.
Use of the port series mode blocked under CBuilder RAD Communication with the robot to the Modbus Protocol, This is a c++ program which serves as a force a bit of %M65. And also to calculate the CRC16 at the end.
This seems like a fairly straight forward assignment. Load up a file that contains a series of int values stored in ASCII and print out the ASCII characters to the console.
The problem I am having is that I am getting the numerical value of bytes ("40" for 10 numerical values, "200" for 50 values). The numbers are generated randomly by another file, but I can control how many numbers are generated. For example, if I type in:
I'm expected to get a starting minimum input, and also an ending maximum output (for example: 21, and 25). From here, i have to give output using all the numbers (in a row) between the min and max numbers.
(for the same example: 21 22 23 24 25)
I assumed I would want to create an array using a variable, but i'm not sure of that either.
The problem deals with writing a program to geta series of integers from a user and storing those values into an array. Then use a function called selection_sort, when given an array with n elements, the function must sort the array from smallest to largest values.
I have code, and im trying to get it to compile but im getting these implicit declaration errors and conflicting types. Here is my code and the compiler errors.
