The magnitude is increasing in the leftward direction. What we really need to do, beyond just evaluating the acceleration at time 5.5, we also have to evaluate the velocity to see if it's going in the left or the rightward direction. Let's evaluate the velocity. The velocity at 5.5, and we'll just get our calculator out again, velocity at 5.5, this is our velocity function, is going to be equal to 2 times the sine of, let me write it this way just because I want to make sure I get my parentheses right, 2 times the sine, let me write it this way, 2 sine of e to the 5.5, that's our time, divided by 4, so I did that part right over here, I'm going to close the 2 as well, and then plus 1. This is our velocity. Our velocity at time 5.5 is negative, so negative 0.45, roughly. This is negative, velocity is negative.
