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>
Essentially, the Mongols weren't very involved with Afro-Eurasia affairs. They preferred their own ideals and rejected foreign intervention many times. Though, the Mongols did invade African and Eurasian territory, but they failed many times. They allowed different religions to be practiced, but they did not tolerate their conquered people to have different overall views from them. The main feature was their tolerant nature towards other religions.
Hope this helped a little bit! Good luck on AP World History :)

He stated that United States should provide support to free people who are continuously resisting and showing oppressiveness against outside pressure or armed minorities.
<u>Explanation:</u>
President Harry S Truman provided 18 minute speech before joint session of congress on 12th March 1947.
Truman stated that U.S. should provide all aids (financial/political/military) to nations which are under threat from internal or external forces. Truman Doctrine marked change in U.S. international policy to containment from isolationism. As an immediate effect in 1947, his effort helped Greek and Turkish to fight against communist.
