The document discusses different types of integral equations. It defines integral equations as equations where an unknown function appears under one or more integral signs. It classifies integral equations as Fredholm equations of the first and second type, and Volterra equations of the first and second type based on whether the limits of integration are fixed or one limit is not fixed, and whether the unknown function is only inside or also outside the integral. It provides examples of some common integral functions that arise in solving integral equations.

This document discusses the present continuous and past continuous tenses in English. It provides the structure and examples of sentences using these tenses, including questions and negative forms. The present continuous is used to talk about something happening now, and is formed with the present tense of the verb "to be" plus the verb ending in "-ing". The past continuous describes something that was happening at a specific time in the past and uses the past tense of the verb "to be" plus the "-ing" form of the main verb.
La Unión Europea ha acordado un paquete de sanciones contra Rusia por su invasión de Ucrania. Las sanciones incluyen restricciones a las transacciones con bancos rusos clave y la prohibición de la venta de aviones y equipos a Rusia. Los líderes de la UE esperan que las sanciones aumenten la presión económica sobre Rusia y la disuadan de continuar su agresión contra Ucrania.
