well 5/12 = 3/12 + 2/12 right?

..Yeah

and
3/12 is 1/4
2/12 is 1/6

Mhm

I understand that far.. Kind of

That makes sense so far, it's usually what follows that ends up looking like Chinese. >.<

Well then you can use an identity...

the bottom one should work

Do you mind showing me how it would work out?.. >.< Sorry

No its fine =) as long as you help me

what would you use for u?

what about v?

so u can be 1/4 and v can be 1/6

Yep! make sure you use (1/4)* pi\[\tan ({\pi \over 4} + {\pi \over 6})\]

u = \(\pi \over 4\)
v = \(\pi \over 6\)

we end up with|dw:1354678186124:dw|

tan(pi/4) = 1
tan(pi/6) = 1/sqrt(3)

Makes sense so far.

then substitute those numbers in

wait a minute.. something is isn't quite right

Erm, make the fractions rational?

the bottom + should actually be a -

OOOH. Right. Ohgawd. I'm so not ready for my test. lol

@satellite73 whats the best way to simplify this?

Lol..That's the step that keeps throwing me off.

..Um any break downs for it?..
