Equations of the form <italic>du</italic>/<italic>dt</italic> = <italic>g</italic>(<italic>u</italic>(<italic>t</italic>), <italic>u</italic>(<italic>h</italic>(<italic>t</italic>))) arise in a number of scientific contexts. The authors point out some interesting properties of the solution of <italic>u</italic>′(<italic>t</italic>) = -<italic>u</italic>(<italic>t</italic> - 1 - <italic>k</italic> sin <italic>ωt</italic>) + sin <italic>at</italic>. These properties were obtained by means of… CONTINUE READING
