Answer 2

To find the values of the given expression when x = 10, we first need to clarify the expression, as it seems to contain some typographical errors. Based on the provided equation, I assume you meant the following expression:

(1) sin(x) / (1 - cos(x)) - (1 + cos(x)) / sin(x)

To evaluate this expression at x = 10, we simply substitute x with 10 and perform the calculations:

(2) sin(10) / (1 - cos(10)) - (1 + cos(10)) / sin(10)

Now, let's calculate the numerical value for expression (2):

sin(10) ≈ 0.1745 cos(10) ≈ 0.9848

(3) Therefore, expression (2) becomes:

0.1745 / (1 - 0.9848) - (1 + 0.9848) / 0.1745

Now, let's simplify it further:

0.1745 / (-0.9848) - (1.9848) / 0.1745

Now, perform the calculations:

-0.17717 - 11.385

Finally, we get the value of the expression at x = 10:

-11.56217

So, the value of the given expression when x = 10 is approximately -11.56217.
