Abstract
In this paper, we prove quantitative theorems for the number of sign changes for the sequences {λ(p)} and {λ(n)} where λ(n) are the normalised Hecke eigenvalues of the primitive holomorphic cusp form f. Also we prove quantitative theorem for the number of sign changes for the sequence {λ(n)} where λ(n) are the Hecke eigenvalues of a Maass cusp form f for the full modular group.
