I am confused with this equation derivation

    I am confused as to how that square root transformed into 3/2 power... Isn't it suppose to be 1/2 power if it's a square root?

    The term on the right with the 3/2 power is the result of the differentiation stated by the term on the left.

    Ahh of course >.< I can't believe I didn't see that. I thought the variables could become a part of the differential d/dt without differentiating the entire equation... My mathematical mistake! lol
