Question

Write a Matlab program calculating A = (1/6626 1b- please use plot, subplot comments FOR THİS EQUATION : f(x) = In ( ) [x3-6256/(00861

Answer 1

1.)

• A can be calculated in two ways: Using for loop and without using for loop

A using for loop:

• Set A = 0 and add each term of summation to A

A = 0; %set A to 0

for i = 6:56

A = A + (1/factorial(6))^6*exp(6); %add each summation terms to A

end

disp(A) % display A

output:

A = 0; $set A to o for i = 6:56 A = A + (1/factorial (6))*6*exp(6); fadd each summation terms to A end disp (A) $display A 1.4769e-13

without using for loop

• Multiply the summation term (56-6+1) times to get A

%multiply summation terms (56-6+1) times to get A

A =(56-6+1)*(1/factorial(6))^6*exp(6);

disp(A)

output:

&multiply summation terms (56-6+1) times to get A A = (56-6+1) * (1/factorial(6))*6*exp(6); disp (A) 1.4769e-13

1b.)

• Define a function handle to calculate f(x)
• Then , plot f(x) for range of x. Here we will plot in the range -10 to 10

program:

%function handle to calculate A

f = @(x)log(6/12)*(x.^(3*6)*exp(56/cos(6)));

%range to plot f(x)

x = -10:10;

%plot f(x)

plot(x,f(x))

xlabel("x")

ylabel("f(x)")

title("f(X)")

grid on

output:

х1042 f(x) о -5 f(x) -10 -15 -10 -5 0 5 10 х
