Se quiere diseñar una ventana como la de la figura, siendo el triángulo superior un triángulo equilátero y su perímetro 10 m. Determinar las dimensiones para que entre la mayor claridad posible, es decir, el área sea máxima. 1º Escribir la función objetivo en función de la longitud de la base del rectángulo: f(x)= El problema consiste en hallar el máximo absoluto de la función f(x) en el intervalo ( , ). 2º Encontrar el punto estacionario: x1= 3º Comprobar la naturaleza del punto estacionario: f′′(x1)= Es un punto de inflexión. Es un máximo relativo. Es un mínimo relativo. 4º Calcular las dimensiones de la ventana de área máxima: a) Base del rectángulo: m. b) Altura del rectángulo: m.
