My question is "verify that v defined by

v = 49/40 - 1/5(x^4 - 6x^2y^2 + y^4) is harmonic and that, when |x|<1 and |y|=1, -0.025 <= v - 1 - x^2 <= 0.025".

How do I show the function is harmonic? I think I have to transform it into a sine/cosine function but I don't know how.

What would be the most efficient frequency/medium to send energy collected by satellite to the earth's surface? (Assuming a mechanism can be derived to convert a useful amount of power from the solar spectrum present outside the atmosphere)
As so much more energy is available outside the atmosphere surely this is a future solution?

Just say I am a student of evolution and you were an evolution teacher...how would you explain this. Yes I know it took millions of years, but if you could look at the process and I guess put it into supper sonic fast forward how would the process take place. I mean losing the long tail, the hairy body, developing the higher brain intelect and all the other changes that had to occur for humans to evolve. Is anybody familure with this evolving process and how to accurately describe it?
