How can I plot This ?

I have : x= [ 0.2 :0.1 : 0.6 ] and y = 4 * (sqrt(1 - x.^2)) / (2*pi*x)

I need to plot This equation for the interval of x from 0.2 to 0.6 ,and it aint working for me !!!

please help ,, thank you

This shoul have worked ,, but it didnt :

for x = [ 0.2 :0.1 :0.6] y = 4 * (sqrt(1 - x.^2)) / (2*pi*x) plot (x,y) end !!

No, what it did is that it did not work as you expected. You are always erasing the previous plot if you do not use hold on. And even if you did, you would have plotted some points, not a line.

Please accept an answer if it helped you. Please look at the documentation on the plot function

 doc plot
 doc hold

    x = 0.2:0.01:0.6;
    y = 4*(sqrt(1-x.^2))./(2*pi*x);
    plot(x,y)

You should always post your code.

What does "it ain't working" mean?

x= [ 0.2 :0.1 : 0.6 ] ; 
y = 4 * (sqrt(1 - x.^2)) ./ (2*pi.*x);
plot(x,y);
