Thanks guys. Some of these answers are flawless. I mean I really get it. That being said:

This question has a picture of two triangles side by side. There are no degree measures nor angles given, and the smallest triangle is located on the left.

The base of the smallest triangle is labeled "s." and the base of the largest triagle is labeled "S"

Question:
In the figure above, if the area of the triangle on the right is twice the area of the triangle on teh left, then in terms of s, S =?

I need find he coefficients C2 and C1 from the wavefunction
PSI(x,0) = C2 |2> + C1 |1>

for harmonic oscillator of mass m and frequency w

|2> and |1> are normalized eigen functions for n = 2 and n = 1

Find the coefficients C2 and C1 such that the expectation value for the total energy, for |PSI(x,0)> equals = 2(h bar)w

and also...
Write the expression for the time dependence of PSI(x,t)
Calculate the probability to find system in state |2> as a function of time

Calculate as a function of time
Calculate as a function of time

Whatever help is possible is GREATLY appriciated.
