Formulae of Vector Analysis

Authors: A. V. Serghienko

We derive the formulae for the sine and the cosine of the sum, not using the notions of scalar and vector products, and using only the definitions of the sine and the cosine. We derive the formulae for the gradient operator, the divergence and the Laplace operator in different orthogonal coordinate systems, not using any additional constructions like Lame coefficients, and using only the definitions of the sine and the cosine.
