En un colegio hay una sala de lectura que tiene 16 mts. de largo y 9 mts. de ancho, pero el director quiere construir una sala cuadrada con la misma área. Si el área total de la sala es 144 mts ¿Cuánto medirá cada lado de la sala?

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
