Question

1-(cos^2 x+sin^2 x),при x=π/3

Answer 1

Так как по основному тригонометрическому тождеству:

cos^2 x + sin^2 x = 1

то при любых значениях х пример имеет вид:

1 - (cos^2 x + sin^2 x) = 1 - 1 = 0

Ответ: 0

Answer 2

Let's break down the expression step by step:

1 - (cos^2(x) + sin^2(x))

According to the Pythagorean identity, cos^2(x) + sin^2(x) = 1. Therefore, the expression becomes:

1 - 1

And the result is:

0

So, when x = π/3, the value of the expression 1 - (cos^2(x) + sin^2(x)) is 0.
