Bretschneider's formula

Heron’s formula: What is the hidden meaning of 1 + 2 + 3 = 1 x 2 x 3 ?

Today's video is about Heron's famous formula and Brahmagupta's and Bretschneider's extensions of this formula and what these formulas have to do with that curious identity 1+2+3=1x2x3. 00:00 Intro 01:01 1+2+3=1x2x3 in action 02:11 Equilateral triangle 02:30 Golden triangle 03:09 Chapter

The Bretschneider von Staudt formula for a quadrilateral | Rational Geometry Math Foundations 132

Brahmagupta's formula gives the area of a cyclic quadrilateral in terms of its four (outside) `lengths', and the CQQ theorem was a logically correct reformulation of that result, using quadrances instead of `distances'. But what about a general quadrilateral? This is a redo of last week's

Markus Reiß (HU Berlin) -- Nonparametric estimation for SPDEs via localisation

We shall first discuss differences for parametric drift estimation between stochastic ordinary and partial differential equations (SODEs/SPDEs). For parabolic SPDEs a classical estimation approach is based on the spectral decomposition of the generator, which is assumed to be known (at lea

Euler's Formula for the Quaternions

In this video, we will derive Euler's formula using a quaternion power, instead of a complex power, which will allow us to calculate quaternion exponentials such as e^(i+j+k). If you like quaternions, this is a pretty neat formula and a simple generalization of Euler's formula for complex
