So this is the limit as x approaches 0 from the left-hand side of 1 minus 2 sine of x. Now sine of x is continuous. It's a continuous function. 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.
