@tomleslie hello. actually T is a mistake from me. It should t(t) and from the previous solution that you have made, have some mistakes. the value of y=0.1,0.02,0.3.. can you solve it again?

@tomleslie is it true what I do here? I means for second and third graph is similar? actually here I want to create 3 graphs with different gamma(y) to see the comparison.
