## Calculus I in a nutshell, integrals of powers of trig and hyperbolic trig. part 2

here we look some at even powers of sine, cosine, a bit about hyperbolic analogs, and secant and tangent as manageable given calculus I techniques.

## AS/A-Level Hyperbolic functions – Proofs of the Derivatives of Inverse Hyperbolic functions

This video tutorial explains how to prove the results of the Inverse Hyperbolic functions.

## Mathematics – Study of Functions 1: The Hyperbolic Function

This is the 6th lesson in the series, “Study of Functions 1.” This lesson explains that the hyperbolic function and its graph, the hyperbola, is the third family of functions we study. It further describes how to draw a hyperbola and examines its symmetry properties. Source: Mindset Network

## AS/A-Level Hyperbolic functions – Derivatives of Inverse Hyperbolic functions examples

This video tutorial goes through examples of how to differentiate functions containing Inverse Hyperbolic terms.

## Teaching connections between Algebra and Geometry II

This is the second half of a talk I gave to maths teachers at the 2015 annual meeting of MANSW. In it I explain some aspects of the intimate correspondence between algebra and geometry that might contribute to a resurgence of interest in geometry as a core subject for school students. In particular in this…

## Geometry of Parabolic and Hyperbolic Orbits

Before we can do the math for interplanetary transfers, we have to learn a little about open orbits and some of the associated terminology. This video walks you through the geometry of parabolas and hyperbolas and shows you how to calculate things like escape speed and hyperbolic excess speed.
