Abstract: | The rate of uniform strong approximation of Marcinkiewicz type for multivariable continuous functions is obtained in this
paper as follows: where Sj(f) denotes the square partial Fourier sum of f and Ej(f) denotes the square best approximation of f by trigonometric polynomials of degree (j,j,…,j), j=0,1,2,…
