To find the displacement between t=0 and t=1, we want to plug 0 & 1 into the equations, then find the different in the answers.
<u>When t = 0:</u>
x = 4 cos(π(0)+π/4) → π · 0 = 0, so therefore:
x = 4 cos (π/4) → cos (π/4) = √2/2
x = 4 (√2/2)
x = 4√2/2 → 4 divided by 2 = 2, so we can simplify this to
x = 2√2
<u>When t = 1:</u>
x = 4 cos(π(1)+π/4) → π · 1 = π, so therefore:
x = 4 cos (π + π/4) → π + π/4 = 5π/4, so therefore
x = 4 cos (5π/4) → cosine of 5π/4 = -√2/2
x = 4 · -√2/2
x = -4√2/2 → -4 divided by 2 = -2, so we can simplify this to
x = -2√2
<u>Answer</u>: Then, we find the difference between x(0) and x(1), which is x(1)-x(0) =
-√2/2 - √2/2 = <u>-√2</u>
In this case, I will choose the first question.
The story "The Lady, or the Tiger?" is a short story that describes a fictional place. In this place, the King is "semi-barbaric." The main reason why the king is described in this way is because the king can be quite cruel to his people, but can also propose progressive, positive ideas. This duality is expressed throughout the story. It is also seen in the character of the princess. The princess is half-barbaric, as she is hot-tempered and jealous. However, she is also in love and is very passionate, which are positive qualities.
It is possible for someone to be half cruel while also being half not. In the story, this is explained by the fact that these "barbarians" received some influence from the Romans, making them more civilized. However, this can also be explained by the fact that humans are naturally complex. They have various sides to them, and are equally capable of great things and of negative things. This is evident in the story.
