First order periodic problems,placing a Landesman Lazer type inequality on our nonlinearity . we will establish the existence of nonnegative solutions to (1.1). Of course analogue results could be obtained for nonpositive solutions. The proof is based on a technique initiated by Mawhin [4, chapter 6] and extended by Nkashama and Santanilla [7] in the early 1990’s.
