Muy bien. Las imágenes seran el resultado de aplicar el seno a un número, entonces, el recorrido o imagen coincide con el de la función seno.

Atención, las imágenes son el resultado de aplicar el seno a un número, entonces, el recorrido coincide con el de la función seno. Les imágenes de la función seno no se multiplican por #a.

Atención, al multiplicar el ángulo por #a antes de aplicar el seno, estamos modificando el período. <br />
