- Simplify the expression to (-\frac{{\cos^2x}}{{\sin^2x + 1}}).To simplify (\frac{{\sin^2 x - 1}}{{1 + \sin^2 x}}), you can use trigonometric identities. One approach is to recognize that (\sin^2 x + \cos^2 x = 1). Rearranging this identity, we get (\sin^2 x = 1 - \cos^2 x). Substituting this into the given expression:
[\frac{{\sin^2 x - 1}}{{1 + \sin^2 x}} = \frac{{(1 - \cos^2 x) - 1}}{{1 + (1 - \cos^2 x)}}]
Now, simplify the numerator and denominator:
[\frac{{(1 - \cos^2 x) - 1}}{{1 + (1 - \cos^2 x)}} = \frac{{1 - \cos^2 x - 1}}{{1 + 1 - \cos^2 x}}] [= \frac{{- \cos^2 x}}{{2 - \cos^2 x}}]
Thus, the simplified form of (\frac{{\sin^2 x - 1}}{{1 + \sin^2 x}}) is (\frac{{- \cos^2 x}}{{2 - \cos^2 x}}).

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.
