Answer:
θ = π + periods of 2π
Sin (π + 2π) = 0
Cos (π + 2π) = -1
Tan (π + 2π) = 0
Step-by-step explanation:
Sin (θ)=0 implies that θ only can be 0 or π plus periods of 2π:
θ = 0+2π
θ = π+2π
For Cos(θ) the values only can be:
Cos (0+2π) = 1 and
Cos (π+2π) = -1
from this, only Cos (π+2π) < 0
So θ only can be θ=π+2π
2+2 = 4. Bro it was so hard. Did i helped you?
B) because if you round your numbers, -18 1/4 is -18 and 2 2/3 rounds up to positive 3
There would be 8 ones, 4 fives, 12 tens, and 4 twenties. That together would be about $228
