The present work tries to give account of the investigations realized in the context of the mathematics in the engineering of control, specifically in the area of the electrical and electronic engineering. Therefore, this article shows the poor application of mathematics, in the industrial environment, specifically in differential equations, the relevance of the subject of study within the area of Educational Mathematics is justified and the background is described. Necessary, to make a didactic proposal of the differential equations in the transmission lines. Research is supported by constructivism, meaningful learning and mathematics in the context of science. Which is the result of investigating how deep the applications are in the industrial environment, according to studies conducted in different companies in the Tula-Tepeji region, with the help of an exploratory research instrument applied directly to engineers in practice. Therefore, it is considered pertinent to highlight that this work is the result of the line of research cultivated by the academic body.
