A cusp form f(z) of weight k for SL2(ℤ) is determined uniquely by its first ℓ := dim Sk Fourier coefficients. We derive an explicit bound on the nth coefficient of f in terms of its first ℓ coefficients. We use this result to study the non‐negativity of the coefficients of the unique modular form of weight k with Fourier expansion Fk,0(z)=1+O(qℓ+1).
