I am getting error as all evaluations resulted in either an error or a complex result

Hi all,

I am getting an error as all evaluations resulted in either an error or a complex result

when I try plot a 2D graph in which,

x-axis ranges from 0.01 to 1

y-axis is logarithmic.

I attached my code below.

Could you please tell me how to overcome this error ?

y-axis must be logarithmic and x-axis is normal values ranging from 0.01 to 1.

If I plot regularly, the values of f2(y) are negative. You can't have the log of a negative number.

If I plot the negative and make the vertical scale log, you get:

Hi vetri veeran,

you have to use the logarithmic scale for the x-axis only.
