all right thanks. I was looking if there were easy method.

comment Find min-max for slope in linear fit
thank you for answer. Could it be possible to add error values for $x$ values too?

comment intermediate steps of simplification of algebraic expression without evaluation
@AlexeiBoulbitch that gives the final answer, I don't want the final answer. I want the intermediate step, collect the variables by factoring $c_1$ and $c_2$ so that I can copy steps from mathematica instead of writing the entire step.

comment step by step interactive indefinite integral
@VahagnPoghosyan when i was in HS, if i couldn't solve an indefinite integral, i would check the answers on the last page of my textbook and differentiate and construct the answer. But I found it so different from the way it is generally solved, that I gave away that approach. LOL ... it's not nice. But I have to admit, it is equivalent solution.

comment step by step interactive indefinite integral
@VahagnPoghosyan yes i thought of that too ... but if I post that as solution, that will definitely get rejected. I mean I just want to know if it is possible or not. I don't know coding in Mathematica and although I have heard that Risch algorithm is used to find closed solution of Indefinite integrals, so far I haven't encountered myself. If it's not easily done then ... i should give up.

@rm-rf no this is not typo issue, I wanted to ask how would I get that value out of the complicated answer MMA gives me.
