Привет!))

$\cos( \frac{\pi}{2} ) - \sin( \frac{3\pi}{2} ) + \tan(2\pi) + \cot( \frac{3\pi}{2} ) = 0 - ( - 1) + 0 + 0 = 1$

Answer 3

Let's break down the expression step by step:

1. cos(90°): The cosine of 90 degrees is 0.

2. sin(270°): The sine of 270 degrees is -1.

3. tan(180°): The tangent of 180 degrees is 0.

4. cot(270°): The cotangent of 270 degrees is 0 because cotangent is the reciprocal of tangent and tangent of 270 degrees is undefined.

Adding these values together:

$0 - (-1) + 0 + 0 = 1$

So, the value of the given expression is $1$.
