Exercise
$\lim_{x\to\infty}\:\frac{\left(3\left(x-2\right)\cos\left(3x\right)\right)}{x^2+6x+9}$
Step-by-step Solution
Learn how to solve problems step by step online. Find the limit of (3(x-2)cos(3x))/(x^2+6x+9) as x approaches infinity. The trinomial x^2+6x+9 is a perfect square trinomial, because it's discriminant is equal to zero. Using the perfect square trinomial formula. Factoring the perfect square trinomial. The limit of the product of two functions is equal to the product of the limits of each function.
