The Taylor series expansion for ax is: Write a MATLAB program that determines ax using the Taylor series expansion. The program

asks the user to type a value for x. Use a loop for adding the terms of the Taylor series. If cn is the nth term in the series, then the sum Sn of the n terms is . In each pass calculate the estimated error E given by . Stop adding terms when . The program displays the value of ax. Use the program to calculate: (a) 23.5 (b) 6.31.7 Compare the values with those obtained by using a calculator.

Answer: (a). 11.3137

(b). 22.849

Explanation:

Provided below is a step by step analysis to solving this problem

(a)

clc;close all;clear all;

a=2;x=3.5;

E=10;n=0;k=1;sn1=0;

while E >0.000001

cn=((log(a))^n)*(x^n)/factorial(n);

sn=sn1+cn;

E=abs((sn-sn1)/sn1);

sn1=sn;

n=n+1;

k=k+1;

end

fprintf('2^3.5 from tailor series=%6.4f after adding n=%d terms\n',sn,n);

2^3.5 from tailor series=11.3137 after adding n=15 terms

disp('2^3.5 using calculator =11.3137085');

Command window:

2^3.5 from tailor series=11.3137 after adding n=15 terms

2^3.5 using calculator =11.3137085

(b)

clc;close all;clear all;

a=6.3;x=1.7;

E=10;n=0;k=1;sn1=0;

while E >0.000001

cn=((log(a))^n)*(x^n)/factorial(n);

sn=sn1+cn;

E=abs((sn-sn1)/sn1);

sn1=sn;

n=n+1;

k=k+1;

end

fprintf('6.3^1.7 from tailor series=%6.4f after adding n=%d terms\n',sn,n);

disp('6.3^1.7 using calculator =22.84961748');

Command window:

6.3^1.7 from tailor series=22.8496 after adding n=16 terms

6.3^1.7 using calculator =22.84961748

cheers i hope this helped !!!

Given positive integer numinsects, write a while loop that prints that number doubled without reaching 100. follow each number w
ELEN [110]
Please provide the language you're using when you ask for programming help, otherwise you aren't going to get the answer that you are looking for.

Here it is in Java, and I'm assuming the number is given via user input? Otherwise, just remove the user input function and replace the integer with a value of your choice. Note, that this isn't the full code; only what is relevant to the question.


public static void main(String[] args) {
    int num = numInput(10);
    printDoubles(num, 100);  // You can create a user input function for
                                             // maxValue if you wanted to.
}

/**
 * Receives user input between 0 and the absolute value of maxInput.
 * @param maxInput The largest absolute value that can be input.
 */
private static int numInput(int maxInput) {
    Scanner sc = new Scanner(System.in);

    maxInput = Math.abs(maxInput);

    int num = 0;
    while (!(num > 0 && num <= maxInput)) {
        num = sc.nextInt();

        if (!(num > 0 && num <= maxInput)) {
            System.out.println("Input too small or too large");
        }
    }

    return num;
}

/**
 * Continues to print out num doubled until maxValue is reached.
 * @param num The number to be printed.
 * @param maxValue The maximum value (not including in which num can                                       be doubled to.
 */
private static void printDoubles(int num, int maxValue) {
    if (num >= maxValue) {
        System.out.println("No output.");
    }

    while (true) {
        if (num >= maxValue) {
            break;
        }

        if (num < maxValue) {
            System.out.print(num + " ");
        }

            num *= 2;
    }

    System.out.println();
}
