- Abstract
The article "Problems and Solutions" presents a section in the Gazette of the Royal Spanish Mathematical Society, led by Óscar Ciaurri Ramírez and Emilio Fernández Moral. Solutions are requested for mathematical problems that cover topics such as integrals, triangles, matrices, and equations. The names of the proposers of each problem are mentioned, as well as the solutions proposed by Emilio Fernández Moral and César Beade. The presented problems include finding the coordinates of a point in a quadrilateral inscribed in a circumference and calculating the limit of an integral. It is also proposed to prove the existence of two congruent and symmetrical triangles with respect to their common circumcenter, which have their vertices on the sides or extensions of the sides of a triangle ABC and whose sides are perpendicular to the sides of ABC. Additionally, a problem related to probability in a game of drawing balls of different colors is solved.
