Answer : True

Explanation: Vectors can hold, data of the same type and can automatically expand accordingly and change it’s size. The date stored in vectors should be linear.

- The syntax for vector is vector<int>v;

- Mostly this is used in C++ as an alternative to arrays

- If you want to use vector in your program then define it in the header first i.e.

#include <vector>

- Push back is a function, that is used to insert an element into the vector

- Pop back removes the element from the vector

Using Matlab programming I need to rotate the line defined by x,y by 45 degrees around 2,2

belka [17]

Answer:

% here x and y is given which we can take as

x = 2:2:10;

y = 2:2:10;

% creating a matrix of the points

point_matrix = [x;y];

% center point of rotation which is 2,2 here

x_center_pt = x(2);

y_center_pt = y(2);

% creating a matrix of the center point

center_matrix = repmat([x_center_pt; y_center_pt], 1, length(x));

% rotation matrix with rotation degree which is 45 degree

rot_degree = pi/4;

Rotate_matrix = [cos(rot_degree) -sin(rot_degree); sin(rot_degree) cos(rot_degree)];

% shifting points for the center of rotation to be at the origin

new_matrix = point_matrix - center_matrix;

% appling rotation

new_matrix1 = Rotate_matrix*new_matrix;

Explanation:

We start the program by taking vector of the point given to us and create a matrix by adding a scaler to each units with repmat at te center point which is (2,2). Then we find the rotation matrix by taking the roatational degree which is 45 given to us. After that we shift the points to the origin and then apply rotation ans store it in a new matrix called new_matrix1.

What is missing link describe briefly with an example class 11?

allsm [11]

A missing link is a long-extinct organism that filled in a gap between closely related species that now coexist on Earth, such as between apes and humans or reptiles and birds.

A possible or recent transitional fossil is referred to as the "missing link." In the media and in popular science, it is widely used to describe any novel transitional form. Initially, the expression was used to describe a hypothetical transitional form that existed between anthropoid ancestors and anatomically modern humans. The term was influenced by both the pre-Darwinian evolutionary theory known as the Great Chain of Being and the now discredited notion that simple species are more primitive than sophisticated ones. Human evolutionary phylogenetic tree. Since evolutionary trees only hold information at their tips and nodes, and the rest is relied on conjecture rather than fossil evidence, geneticists have supported the idea of the "missing link." But anthropologists no longer like it because of what it suggests.

Integers and booleans. Write a program RightTriangle that takes three int command-line arguments and determines whether they con

icang [17]

Answer:

The programming language is not stated;

I'll answer using C++

#include<iostream>

#include<cmath>

using namespace std;

int main()

{

int side1, side2, side3;

cout<<"Enter the three sides of the triangle: "<<endl;

cin>>side1>>side2>>side3;

if(side1<=0 || side2 <= 0 || side3 <= 0) {

cout<<"Invalid Inputs";

}

else {

if(abs(pow(side1,2) - (pow(side2,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

else if(abs(pow(side2,2) - (pow(side1,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

else if(abs(pow(side3,2) - (pow(side2,2) + pow(side1, 2)))<0.001) {

cout<<"Right Angled";

}

else {

cout<<"Not Right Angled";

}

return 0;

}

Explanation:

The following line declares the three variables

int side1, side2, side3;

The next line prompts user for input of the three sides

cout<<"Enter the three sides of the triangle: "<<endl;

The next line gets user input

cin>>side1>>side2>>side3;

The following if condition checks if any of user input is negative or 0

if(side1<=0 || side2 <= 0 || side3 <= 0) {

cout<<"Invalid Inputs";

}

If otherwise

else {

The following if condition assumes that side1 is the largest and test using Pythagoras Theorem

if(abs(pow(side1,2) - (pow(side2,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

The following if condition assumes that side2 is the largest and test using Pythagoras Theorem

else if(abs(pow(side2,2) - (pow(side1,2) + pow(side3, 2)))<0.001) {

cout<<"Right Angled";

}

The following if condition assumes that side3 is the largest and test using Pythagoras Theorem

else if(abs(pow(side3,2) - (pow(side2,2) + pow(side1, 2)))<0.001) {

cout<<"Right Angled";

}

If none of the above conditions is true, then the triangle is not a right angles triangle

else {

cout<<"Not Right Angled";

}

}

return 0;
