So this is going to be the same thing as 1 minus 2 sine of 0, which we've already figured out, which is exactly equal to 1. So this is equal to 1. So the value of the limit as we approach from the left is the same as the value of the function. Now let's do it as we approach from the right, as we approach from values of x greater than 0. So let's think about the limit as we approach 0 from the right of f of x. So here, we're dealing with values of x that are larger than 0. So we're dealing with this case right over here.
