## How Behavior Spreads: The Science of Complex Contagions, by Damon Centola, a review

NB. This book was sent to me as a review copy. From Princeton University Press The idea of this book is relatively simple, but the consequences are huge, and in fact some of the ideas are far more subtle and complex than they may first appear. Essentially [...]

## Why did we choose that range for theta when doing trig substitutions?

Remember when we are doing a trig substitution, for instance for an integral with: $latex \sqrt{a^2-x^2}$ We said that we should choose $latex x=a\sin\theta$, which seemed reasonable, but we also said that $latex -\frac{\pi}{2}\le\theta\le\frac{\pi}{2}$. Where did this last bit come from? Well, we want a couple of things to [...]

## Integrals with sec and tan when the power of tan is odd

We went through an example in class today which was $latex \int tan^6\theta \sec^4\theta d\theta$ In this case we took out two powers of sec and then converted all the other $latex \sec$ into $latex\ tan$, which left a function of tan times $latex sec^2\theta d\theta$. We wanted [...]

## Fundamental theorem of calculus example

We did an example today in class which I wanted to go through again here. The question was to calculate $latex \frac{d}{dx}\int_a^{x^4}\sec t dt$ We spot the pattern immediately that it's an FTC part 1 type question, but it's not quite there yet. In the FTC part 1, [...]

## Calculus for the ambitious, by Tom Korner, a review, by Henri Lauri

Amazon link This is a lovely book: strong emphasis on ideas; a lively sense of humour; a sure logical touch; historical detail that is accurate, relevant, yet quirky (takes some doing!). What's not to like? Well, there's this: it is not easy to decide whether to recommend the book to [...]
