The lesson initially addresses basic mathematical functions, highlighting the differences between dependent and independent variables. A classic example is the relationship between weight, mass, and acceleration due to gravity. In this case, mass is the independent variable, and weight is the dependent variable. Multivariable functions are also introduced, such as hydraulic power, which depends on specific mass, flow rate, and manometric head. The study of derivatives is deepened with examples that demonstrate how they represent the variation of one quantity as a function of another, both in point analyses (infinitesimal view) and in finite element computational systems. The difference between simple and partial derivatives is well defined, showing how the partial derivative allows evaluating the influence of one variable while keeping the others constant. Another essential point addressed is the integral, which represents the calculation of the total or global value of a quantity. While the derivative deals with local variations, the integral provides a macro view. Multiple integrals, used in three-dimensional analyses, are also explained didactically. In the final part of the lesson, the main systems of units are discussed: the International System (SI) and the English System. Correct nomenclature standards and symbols are highlighted, such as meter (m), kilogram (kg), second (s), and Kelvin (K), as well as their most common conversions. The importance of knowing how to perform unit conversions is emphasized, with the support of online tools when necessary.
