This is the only relevant term. I could do the rest but it seems that lower math has failed me here. any help appreciated.

each new line should begin with an equals sorry.

What's your question? Is it that the exponent on x changed from -1/2 to 1/2 or are you unable to understand how $\frac 1 6 * \frac 1 {1/2} = \frac 1 3$?

If it's the latter, $\frac a b \cdot \frac c d = \frac{ac}{bc}$.

Have you checked out the khanacademy link that I gave yesterday? Until you get your arithmetic skills up to where they need to be, you won't be able to follow even the simplest calculus explanations.

how did x change from - 1/2 to 1/2.

x didn't change - its exponent changed from -1/2 to 1/2. This was explained in the thread you started yesterday.

$\int x^n dx = \frac{x^{n+1}}{n+1} + C$ if n ≠ -1.

Sorry. I remember posting that thread now. Haven't slept in two days.
