To find the value of sin(sec^(-1)(u/2)), use the identity sin(sec^(-1)(x)) = √(x^2 - 1)/x. So, sin(sec^(-1)(u/2)) = √((u^2/4) - 1)/(u/2). Simplify this expression to get the final result.

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.
