Question:
what is the limit, as x approaches 0, or tan^23x/x^2? (read, tan squared 3x over...)

For your example

		To relate each of the first two fractions to the known limit above we need the quantity inside the sine function, ie 3x to be the same as the quantity in the denominator. Thus multiply the numerator and denominator in each of the first two fractions by 3 to get

Now evaluate this limit.
