Explanation:
we're going to steer this in the direction of well known limit
using the double angle identity:
pattern matching numerator and denominator, and taking the constant term outside the limit
these limits of these individual terms exist and the limit of the product is the product of the limits
You cannot use L'Hopital's Rule for this.
