LIM (x tends to 0) x ^ 2 / (sin ^ 2) * x / 3

X → 0lim x ^ 2 / sin ^ 2 (x / 3) = Lim 9 * x ^ 2 / 9 / sin ^ 2 (x / 3) = 9 * LIM (x / 3) ^ 2 / sin ^ 2 (x / 3) = 9 * Lim [(x / 3) / sin (x / 3)] ^ 2 = 9 * [LIM (x / 3) / sin (x / 3)] ^ 2 according to the important limit: Lim SiNx / x = 1 = 9 * 1 ^ 2 = 9, you are welcome to ask
