So I can usually do these problems fine, but I cant even figure out where to start with this one, prove that:
(1-tan^2x)/(1+tan^2x)=cos2x
I am sure I'm just missing some simple step that'll be obvious once someone points it out, but can anyone help me through the first couple steps here and I'm sure I could finish it off after that.

Ok, I have a three page essay to write for Honors English II about the Hiroshima bombing, and I need a LOT of help...
I just got the assignment today and it's due on monday -_-

I need to know how far the Axis' rule spread, where they'd taken over.

I need to know where Hitler died.

And I need to know about the monumental buildings left up after the bombing of Hiroshima.

Please, I can find the rest of the info, I just need this. Thank you

Flying high like the sun,
Soaring in the blue vastness of
the mountain sky
Descending, diving like a rock dropped out of the heavens,
Screeching as it races fast as light, down at unsuspecting prey,
Plunging into icy water with all of Earth's harshness
Reappearing from the water's darkness,
Climbing up, up into the sky,
Shedding water off its wings, now glistening like diamonds,
as it speeds, higher, higher into the crystal heavens
Stopping its speeding climb,
it peaks, levels and circles once again
The world down below seems to applaud its amazing feat,
the wind whistles with amazement
The water sore from its ripping talons, which slashed the clear water's surface
causing ripples in agony,
making only minimal noise compared to the damage it suffered
