Integrate √x-1 dx

Integrate √x-1 dx

\(\int \sqrt{x-1}dx\)

For this, you do a simple u-substitution.

Set \(x-1\) equal to \(u\), giving you the following expression:

\(\int \sqrt{u}dx\)

With u-substitution, you then take the derivative of \(u=x-1\):

\(du=dx\)

Delta method question!

Delta method question!

Find the derivative of this by the delta method

\(y=x^2+3x-\frac{2}{x}\)

\(\frac{dy}{dx}=\lim _{\Delta x\rightarrow 0}\left(x^2+3x-\frac{2}{x}\right)\)

Apply \(x-\Delta x\) into where you see x's:

Chain rule help

\(y=\sqrt{u^2-1}\)
\(u=4\sqrt{x}\)

Put u into x

\(y=\sqrt{\left(4\sqrt{x}\right)^2-1}\)

Simplify:

\(y=\sqrt{16x-1}\)

Now derive, change to fractional coefficients:

\(y=\left(16x-1\right)^{\frac{1}{2}}\)

Rules of differentiation Discussion

Rules of differentiation Discussion

These rules you have nothing to worry about. They're there to make differentiation easier to do, that's all.

Examples:

#1,2 Let's say you have:

\(f\left(x\right)=x±x^2\)

You differentiate twice:

Find the relationship describing the volume (V) of a cube as a function of the length of the diagona

Find the relationship describing the volume (V) of a cube as a function of the length of the diagonal going through the cube (d).  You MUST show your work in finding this relationship (either by writing it out on paper, or typing it up in Maple).  Enter this as a function in Maple, and evaluate it for a diagonal length of d = 1.2.
