Direct Substitution...

That's all. There's no need for any advanced techniques here.

I'll do it... Here's a step by step of all the relevant theorems of limits that apply.

1. The limit of a sum is the sum of the limits.

2. The limit of a product is the product of the limits.

4. The limit of a constant is that constant

5. The ovious limit

6. The limit of transcendentals

You can see that there is no need for the squeeze theorem.
