Answer:

Go to explaination for the step by step answer.

Explanation:

a)Code

function[y]=operation(x) % this function takes x as input and returns y as output

y=(-0.2*x^3+7*x^2)*exp(-0.3*x)

end

% call this function in command widow by typing operation(value of x) like shown in figure in the first attachment.

b. write a code of above function in one script window and save the code with same name as name of function that is name of script should be saved as operation.Now copy paste the below code in new script window and run the code

clc

clear all

x=-2:.1:6

n=length(x)

for i=1:1:n

a=x(i)

y(i)=operation(a)

end

plot(y,x)

xlabel('X')

ylabel('Y')

Please kindly check attachment for pictorial answers that supports the code.

nadezda [96]

Answer:

Following are code of factorial in python language

def factorial(n): # function

   result=1 #variable

   for x in range(2,n+1): #iterating the loop

       result=result*x  #storing result

   return result #return result

for n in range(10): #iterating loop

   print(n,factorial(n)) #print factorial

Output:

Following are the attachment of output

Explanation:

Missing information :

In the question the information is missing the code is missing which we have to correct it following are the code that are mention below.

def factorial(n): # function

   result=1 #variable

   for x in range(       ): #iterating the loop

       result=  #storing result

   return  #return result

for n in range(  ): #iterating loop

   print(n,factorial(n)) #print factorial

Following are the description of code

  • We have create a function factorial  in this we have pass the one parameter i.e "n".
  • In the for loop we have pass 2,n+1 which has been used to iterating the loop calculating factorial and string the result in the result variable
  • In the main function we have pass the range on which we have to calculated the factorial
  • Finally the print function will print the factorial .

Following are the attachment snip of code in the python language

Write a method maxMagnitude() with two integer input parameters that returns the largest magnitude value. Use the method in a pr
yawa3891 [41]

Answer:

The program in Java is as follows:

import java.util.*;

import java.lang.Math;

public class Main{

public static int maxMagnitude(int num1, int num2){

    int mag = num2;

    if(Math.abs(num1) > Math.abs(num2)){

        mag = num1;

    }

    return mag;

}

public static void main(String[] args) {

 int num1, num2;

 Scanner input = new Scanner(System.in);

 System.out.print("Enter two integers: ");

 num1 = input.nextInt();

 num2 = input.nextInt();

 System.out.println(maxMagnitude(num1,num2));

}

}

Explanation:

The method begins here

public static int maxMagnitude(int num1, int num2){

This initializes the highest magnitude to num2

    int mag = num2;

If the magnitude of num1 is greater than that of num2

    if(Math.abs(num1) > Math.abs(num2)){

mag is set to num1

        mag = num1;

    }

This returns mag

    return mag;

}

The main  method begins here

public static void main(String[] args) {

This declares num1 and num2 as integer

 int num1, num2;

 Scanner input = new Scanner(System.in);

This prompts the user for two integers

 System.out.print("Enter two integers: ");

This gets input for the first integer

 num1 = input.nextInt();

This gets input for the second integer

 num2 = input.nextInt();

This calls the maxMagnitude method and prints the number with the highest magnitude

 System.out.println(maxMagnitude(num1,num2));

}
