Can someone help me with the code to plot this

Can someone tell me how to plot this function on matlab. Every time I input the function and try plotting, the graph does not look right.

Show what you tried. Otherwise, you are just asking us to do your homework for you.

>> x=[0,1];
>> y1=sqrt((sin(x).^2)+exp(-(x/2)))

y1 =

      1.0000    1.1466

>> plot(x,y1)

Answer 1

x = linspace(0,1);

[Ziv Melamed]

Is the y1 function I originally entered correct? When comparing it to the the image which shows the f(x) function.

[Walter Roberson]

You missed a .^2 inside the exp()

[Les Beckham]

You should check your parentheses also. As written, you are taking the square root of the entire expression instead of just the sin^2(x) portion.

Good catch, Les.
