Zoe AustinTo simplify ( \tan(x) \cos(x) ), you can use the trigonometric identity:
[ \tan(x) = \frac{\sin(x)}{\cos(x)} ]
Substitute this identity into ( \tan(x) \cos(x) ) and simplify:
[ \tan(x) \cos(x) = \frac{\sin(x)}{\cos(x)} \cdot \cos(x) ]
[ = \sin(x) ]
So, ( \tan(x) \cos(x) ) simplifies to ( \sin(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.

- Verifying a Trigonometric Identify: cot(pi/2-x)=tanx I am stuck, I used the difference identity for tan, but tan is undefined at pi/2, so would I just substitute the value for cot pi/2 fir tanA in the tan difference formula? Thanks in advance.
