Very interesting entrance questions. However, as for the trigo question, I can't seem to simplify any further than this, which I somehow feel that it can be further simplified.

Whitecorp can you simplify any further?

I know what you mean.In all honesty, your answer looks pretty fine and judging from its graph using the graphic calculator, it is highly unlikely you can simplify it into a spectacularly compact form. I have extended your workings for a condensation into cos4(theta) to make things look less cluttered, but in this respect the pure cos theta variant will be completely absent (which in the strictest sense will not be the proper solution).

Here are my workings:



And here are some hints dropped by them folks at Stanford presumably:

Great to see someone so young being exceptionally competent in trigonometry. Keep it up. Peace.

That's a pretty cool derivation. Anyway I don't really consider myself to be competent in trigonometry lol. In fact, trigonometry is probably one of my weakest area in maths.
