This just simplifies to $-tan(x)$ .

We are given
$\dfrac{tan(-x)csc(-x) }{sec(-x)cot(-x)}$ .

Let's write each trig function in terms of sine and cosine.

$\dfrac{ \frac{sin(-x)}{cos(-x)} \frac{1}{sin(-x)}}{ \frac{1}{cos(-x)} \frac{cos(-x)}{sin(-x)} }$

Cancel sin(-x) in the numerator and cos(-x) in the denominator.

$\dfrac{\frac{1}{cos(-x)}}{\frac{1}{sin(-x)}}$

Simplify.

$tan(-x)=-tan(x)$

Answer:

The hourly drop between the two times is 1/40

Step-by-step explanation:

Firstly, we need to find the difference in time between 9 pm and 6:36 am

That would be 9 hours and 36 minutes

It would be needed to convert 36 minutes to hours

Mathematically, 60 minutes = 1 hour

So 36 minutes = (36 * 1)/60 = 36/60 = 0.6

So the difference between the two time is simple 9.6 hours

So the total drop during the time is given by 6/25

So the hourly drop will be 6/25 divided by 9.6

= 6/25 * 1/9.6 = 6/240 = 1/40
