Question

-cosx:cosx= сколько будет?

Answer 1

Если х≠π/2+πn,где n∈Z, то можно сократить дробь и будет -1

Answer 2

To simplify the expression (-cos(x)) / cos(x), we can use trigonometric identities. Specifically, we'll use the identity that states:

cos(a) / cos(b) = 1, if a = b

In this case, a = -x and b = x. Since -x is equal to x, we can simplify the expression as follows:

(-cos(x)) / cos(x) = -1

So, the simplified result is -1.
