In this paper, the impact of the partial slip, radiation, and injection/ suction parameters on the flow and heat transfer over a permeable stretching/shrinking sheet has been investigated. The exact solutions for stretching and shrinking sheet are given by unified formulas. Dual solution for shrinking sheet has been discussed. In addition, several comparisons between the current exact results and those in the literature have been introduced for the case of stretching sheet when the slip parameter vanishes. The results are discussed through tables and plots.
