    Experiências geoanalíticas na sala de aula
    (2019-06-29) Saavedra, Beto
    Through the solution of problems in Analytic Geometry, this work aims to discuss the potential of its concepts and formulas, which are often applied mechanically. Furthermore, it seeks to show, with due modesty, that within the teaching and learning process of this discipline there are still new horizons to be discovered and explored. This work is not intended as an introduction to Analytic Geometry, but rather as a review.

    Geometria analítica: equações paramétricas do plano
    (2026-05-28) Saavedra, Beto
    This material presents, in a visual and educational way, the idea of a plane in parametric form in Analytic Geometry. The plane is defined by an initial point (P_0) and by two non-parallel direction vectors, (\vec a) and (\vec b). From the equation (P = P_0 + s\vec a + t\vec b), it is shown that, as the parameters (s) and (t) vary, the points belonging to the plane are generated. Thus, the animation helps students understand how the direction vectors determine the orientation of the plane in space.
