@MhenniBenghorbal: Thanks for the comment. Could you give me some guideline as to how to go about approximating ODEs?

The main confusion being exp integral is defined as a definite intgeral and we have indefinite integrals in our equations.

Thanks @Chinny. There is a typo which gets repeated - $k_2t$ in place of $k_3 t$ in the exponent. Also I do not understand how you used the def. of exp. integral. Could you pl. correct and elaborate? Thanks :)

Hi @ClaudeLeibovici: My main ques. is how we can move from an indefinite integral to a definite integral, as is the case in the definition for $E_\alpha$.

@ClaudeLeibovici: No, from the Wiki defn, I do not see how you arrive at the transformation from gamma to exp.

@ClaudeLeibovici: Can you give me the defn. of $E_{-\alpha}$? Is it the exponential integral?
