Answer 2

Let's break down the expression step by step:

1. sin(pi) = 0 The sine of pi radians is 0.

2. cos(pi) = -1 The cosine of pi radians is -1.

3. tg(pi) = tan(pi) = 0 The tangent of pi radians is 0.

4. ctg(3pi/2) = cot(3pi/2) = 0 The cotangent of 3pi/2 radians is 0.

Now, substituting these values into the expression:

4 * sin(pi) * cos(pi) + tg(pi) - ctg(3pi/2) = 4 * 0 * (-1) + 0 - 0 = 0

Therefore, the value of the expression 4 * sin(pi) * cos(pi) + tg(pi) - ctg(3pi/2) is 0.
