Álgebra Básica (Coursera)

Álgebra Básica (Coursera)

Galileo dijo: "El Universo está escrito en lenguaje matemático y los caracteres son triángulos, círculos y otras figuras geométricas, sin las que es humanamente imposible entender una sola palabra". Para entender el Universo, es necesario plantear leyes que expliquen su comportamiento, como pueden ser las leyes de la gravedad, la propagación del calor, el electromagnetismo, la reproducción celular, el crecimiento poblacional, la propagación de las enfermedades, la variación de los precios de las acciones en la bolsa de valores, el comportamiento de las masas ante un conflicto, etcétera.

Todas estas leyes se plantean utilizando ecuaciones, algunas muy sencillas, otras no tanto. Para poder aplicar estas ecuaciones para resolver problemas, es necesario manipularlas siguiendo ciertas reglas que nos da el álgebra.
Piensa en el álgebra como la gramática, que nos dice cómo traducir nuestras ideas al lenguaje, cómo formar frases y oraciones a partir de palabras, cómo conjugar verbos, a identificar las partes de una oración, las reglas de acentuación, etcétera.
En este curso aprenderás a construir expresiones algebraicas a partir de frases, lo que te permitirá resolver problemas en los que conoces algunos datos numéricos y necesitas encontrar otros.
Podrás plantear y resolver ecuaciones de primer grado, ecuaciones simultáneas y ecuaciones de segundo grado.
Este curso te va a ser muy útil si actualmente estas llevando un curso de álgebra en la escuela y tienes problemas con él. También si ya has estudiado álgebra y necesitas repasarla, ya que necesitas recordarla para tener éxito en otros cursos más avanzados, como Geometría Analítica, Cálculo o Estadística.

Syllabus

WEEK 1
Introducción al álgebra
Al final de este módulo:
• Reconocerás el álgebra como la gramática con la cual las ciencias plantean problemas y buscan soluciones a los mismos. • Escribirás expresiones algebraicas a partir de frases en el lenguaje común que expresen relaciones entre diferentes variables. • Valuarás expresiones algebraicas para números concretos y simplificarlas utilizando las reglas usuales de la aritmética de los números reales.

WEEK 2
Ecuaciones de primer grado y ecuaciones simultáneas
Al final de este módulo:
• Plantearás ecuaciones de primer grado a partir de problemas concretos, para resolverlas usando operaciones algebraicas elementales.

WEEK 3
Polinomios
Al final de este módulo:
• Efectuarás operaciones aritméticas con polinomios a fin de simplificarlos.

WEEK 4
Productos notables y factorización
Al final de este módulo:
• Realizarás productos y factorizaciones de expresiones algebraicas de manera eficiente utilizando las reglas conocidas como productos notables, con la finalidad de emplearlas para resolver ecuaciones de segundo grado.

WEEK 5
Ecuación de segundo grado
Al final de este módulo:
• Plantearás ecuaciones de segundo grado a partir de situaciones concretas. Así mismo, podrás encontrar las soluciones de dichas ecuaciones ya sea factorizándolas como producto de dos ecuaciones de primer grado, o bien, utilizando la ecuación general de segundo grado.
