Answer 1

MATLAB Code:

close all
clear
clc

fprintf('\nQ1\n----------------\n')
A = [35 1 6 26 19 24;
3 32 7 21 23 25;
31 9 2 22 27 20;
8 28 33 17 10 15;
30 5 34 12 14 16;
4 36 29 13 18 11];
min_element = min(min(A(end-2:end,:)))

fprintf('\nQ2\n----------------\n')
h = 1e-3;
x = 0:h:2;
y = sin(0.3*pi*x).^2;
plot(x,y), xlabel('x'), ylabel('y')
title('y = sin(0.3\pix)^2')
area_approx = sum(y)*h
area_actual = integral(@(x) sin(0.3*pi*x).^2, 0, 2)

fprintf('\nQ3\n----------------\n')
B = [16 2 3 13;
5 11 10 8;
9 7 6 12;
4 14 15 1];
num_elements = sum(sum(B <= 10 & B ~= 6))

fprintf('\nQ3\n----------------\n')
C = zeros(100);
l = 2;
for i=l+1:2*l:100
C(:,i:i+l-1) = 255;
end
imshow(C)

Output:

Q1
----------------
min_element =
4

Q2
----------------
area_approx =
1.1564
area_actual =
1.1559

Q3
----------------
num_elements =
9
