Simply, substitute the expression for p in the equation gives us the familiar cosine rule. There are many ways to show this proof, and I could do it using vectors as well but this is just a simple way to show kids and GCSE students....
In this study, we prove the Cosine Rule II for a spherical triangle on the dual unit sphere %S 2 . 2. DUAL NUMBERS AND DUAL VECTORS Definition 2.1. A dual number has the form λˆ := λ + ελ* , where λ and λ* are real numbers and ε stands for the dual unit which is ...
They are widely used in some fields, such as medical diagnosis, pattern recognition and so on. One of the important similarity measures is the cosine similarity measure; it is defined as the inner product of two vectors divided by the product of their lengths. It has been widely studied in...

First, the PCA projection vectors in the model can be obtained by using the Hebbian rule in neural networks. Second, the outputs of the pulsed PCA transform, which are inherently binary, simulate the neuronal pulses in the human brain. Third, like many Fourier transform-based approaches, our ...
The cosine constraint model was established by means of feature vectors, and the double matching constraint was constructed by combining the distance measurement method of feature vectors, thus completing the matching between feature points. The voting mechanism was introduced to improve RANSAC method. ...
