    Simple equations

    Can anyone explain how does the s variable ends up as a denominator? I cant really understand the last equality.

    dq=Tds=>\int_{i}^{f}dq=\int_{i}^{f}Tds aproximately equal to \overline{T}\int_{i}^{f}ds<=>\overline{T}=\frac{_i  q_f}{s_f-s_i}

    you'r solving for Tbar

    q = Tbar(sf-si)

    divide by sf -si to solve for T bar
