We have simulated more than 10{sup 5} extensive air showers (EAS) by CORSIKA code, with a proton as the primary particle. The range of energy for primary particles was selected from 50 TeV to 5 PeV, with differential flux given by dN/dE{proportional_to}E{sup -2.7}. Using the secondary charged particles produced of these EASs, we obtained the function dN{sub sp}({theta},X)/d{theta}, where N{sub sp}({theta},X) is the number of secondary charged particles in EASs as a function of atmosphere depth, X, and zenith angle, {theta}. A sin{theta}cos{sup n(X)}{theta} distribution was obtained for zenith angle distribution of the number of secondary charged particles, where power index, n(X), is a function of atmosphere depth, X. We obtained n(X)=3.02+0.003XlnX-8.28x10{sup -9}X{sup 3}-1.35lnX. We have compared our results with the experimental data of various observatories.
