1) Khrushchev ordered the invasion of Hungary, using 200,000 Soviet troops and 6000 tanks.
y=k/x2
yx2=k
1*102=k
k=100
x=1 y=100
x=2 y=25
x=5 y=4
x=10 y=1
We first want to get every term in terms of the same variable, namely sin(x). to do so, we will use the identity sin^2(x) +cos^2(x) = 1 to get: 4(1-sin^2(x)) -15sin(x) -13 = 0. which we can then rewrite a...
You would first multiply the expression by (3-root(5))/(3-root(5) - which equals 1 - to get (6-2root(5))/14 which then equals 3/7 - (1/7)*root(5) and you are done.
