Help me solve Int of ((6x^2+1)/(8x^3+4x))dx
Having taken Calculus over 35 years ago and did pretty well, I am now a bit stumped in solving this. I have factered 1/4 to the left of the integrand, and let u=2x\^3+1, and then get du/dx=6x\^2,
then substitute back in but get stumped at that point.

How to Create a Custom 2D Physics Engine: Oriented Rigid Bodies - Tuts+ Game Development Tutorial
So far, we've covered impulse resolution, the core architecture, and friction. In this, the final tutorial in this series, we'll go over a very interesting topic: orientation.
In this article we will discuss the following ... | {"url":"http://gamedevelopment.tutsplus.com/tutorials/how-to-create-a-custom-2d-physics-engine-oriented-rigid-bodies--gamedev-8032","timestamp":"2014-04-18T03:00:40Z","content_type":null,"content_length":"96353","record_id":"<urn:uuid:38755d4a-52c2-4728-acf3-32d14f0a6974>","cc-path":"CC-MAIN-2014-15/segments/1398223207... |
Compound Interest (Finite Number of Calculations) - Problem 1
We’re now going to look at a compounded interest question. So basically what we have is a set up where we invest $3000 in an account that earns 4% interest, how much will you have after 4 years if
interest is compounded in a number of different ways?

Tensors with low spectral norm

Consider a tensor $T$ with six indices, $T_{(ii')(jj')(kk')}$, where each index goes from $1$ to $n$. We can think of $T$ as a linear map from $\mathbb{R}^n \otimes \mathbb{R}^n \otimes \mathbb{R}^n$
to itself and consider its spectral norm:

Magnetic Particle Inspection Gets Revitalized

The difficulty with processing ring-shaped parts for aerospace applications is a risk of deformation, or burning or arcing of the part when clamped between contact plates. Correct part processing
