2 sin π + 3 cos π + ctg(π/2)
Since sin(π) = 0, cos(π) = -1, and ctg(π/2) = 0, we can plug these values in:
2 0 + 3 (-1) + 0= -3
Therefore, the result is -3.
2 sin π + 3 cos π + ctg(π/2)
Since sin(π) = 0, cos(π) = -1, and ctg(π/2) = 0, we can plug these values in:
2 0 + 3 (-1) + 0
= -3
Therefore, the result is -3.
