The tan(-x) is the same thing as -tan(x). The tangent function is also the same thing as sin(x)/cos(x), right? So let's rewrite that tan in terms of sin and cos:
![[cos(x)][tan(-x)]](https://tex.z-dn.net/?f=%5Bcos%28x%29%5D%5Btan%28-x%29%5D)
is the same as ![[cos(x)][ -\frac{sin(x)}{cos(x)}]](https://tex.z-dn.net/?f=%5Bcos%28x%29%5D%5B%20-%5Cfrac%7Bsin%28x%29%7D%7Bcos%28x%29%7D%5D%20)
We can now cancel out the cos(x), which leaves us only with -sin(x) remaining. So your answer is A.

Answer:
(D). 28
Step-by-step explanation:
We have been given that the smallest integer that can be divided by the product of a prime number and 7 while yielding a prime number.
We know that smallest prime is 2. The product of 2 and 7 is 14.
Let us divide our given numbers by 14.
(A) 7.
The quotient is not a integer or prime number.
(B). 14
We know that 1 is not a prime number.
(C) 24.
The quotient is not a integer or prime number.
(D). 28
Since 2 is a prime number, therefore, 28 is the smallest integer that can be divided by the product of a prime number and 7 and yield a prime number.
