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.
Answer:a) Mainframes, miniframes, PCs, desktop Internet computing, mobile computing
Explanation: The hierarchy of the computers or computing are in the generation is:-
- Mainframe:-designed for the execution of huge data processing , storage and execution.
- Miniframe:-has similar functioning as the mainframe but on smaller scale and version.
- Personal computer(PC):-It is designed for the individual purpose and according the need of the user.
- Mobile computing:-computing that can be done on the mobile phone similar to the computing on the personal computer
- Internet computing:-the computing of the mobile and computer system with the facility of the internet connectivity.
The <u>camera, projector</u>, invented by the Lumiere brothers in Paris included a <u>phonograph</u>.
- camera, projector, phonograph
<u>Explanation:</u>
Lumiere brothers, French designers and pioneer producers of photographic gear who formulated the early movie camera and projector called the Cinématographe. A cinematograph is a movie film camera, which likewise fills in as a film projector and printer.
The key development at the core of the Cinématographe was the instrument through which film was moved through the camera. It shows moving pictures on a screen. Which goes rapidly enough, an image replaces another too rapidly for the eye to see the change, along these lines shaping a moving picture.
