3tg(0) - 2sin(180) + 3cos(0) + 2ctg(90)
Since tg(0) = 0, sin(180) = 0, and cos(0) = 1, and ctg(90) = 0, we can simplify the expression:
3(0) - 2(0) + 3(1) + 2(0)0 - 0 + 3 + 03
Therefore, the expression simplifies to 3.
3tg(0) - 2sin(180) + 3cos(0) + 2ctg(90)
Since tg(0) = 0, sin(180) = 0, and cos(0) = 1, and ctg(90) = 0, we can simplify the expression:
3(0) - 2(0) + 3(1) + 2(0)
0 - 0 + 3 + 0
3
Therefore, the expression simplifies to 3.
