To solve the equation cos(3x) = √3/2, you can use the inverse cosine function to find the values of x. Start by taking the inverse cosine of both sides of the equation:

cos^(-1)(cos(3x)) = cos^(-1)(√3/2)

This simplifies to:

3x = cos^(-1)(√3/2)

Now, you can solve for x by dividing both sides of the equation by 3:

x = (1/3) * cos^(-1)(√3/2)

This will give you the values of x that satisfy the equation. Keep in mind that the inverse cosine function typically gives values in the range [0, π], so you may need to consider multiple quadrants to find all possible solutions.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
