Answer:

The correct simplification of the given expression  tan(-x){\times}cos(-x) is -sinx.

Step-by-step explanation:

The given expression is:

tan(-x){\times}cos(-x)

Now, simplifying the above given expression, we get

=\frac{sin(-x)}{cos(-x)}{\times}cos(-x) (because tanx=\frac{sinx}{cosx}})

=sin(-x)

Also, we know that sin({-\theta})=-sin{\theta}, tehrefore teh expression becomes

=-sinx

Hence, the correct simplification of the given expression  tan(-x){\times}cos(-x) is -sinx.
