[admins, please! dont delete this thread!
]anyone can help me in proving this trig identity?
sec x + 1 - tan x 1 + cos x
----------------- = ---------
tan x - sec x + 1 sin x
if u have the time....

i know its a bit late to submit this info for you Lord Vimal, but i am a math wiz and this stuff wuz done in high school for me. the way to go about that prob on ur own if your interested is to substitue out the sec and the second sets that go along with sin/cos/tan cosecant/?/cotang ... know wut i mean? i dont remember the defs they should be in ur textbook that like sin+1=cosecant etc ... once you are done swapping them out all you do is cancel and simplify the equation therefore leaving you with a tru statement or a false statement ... if u dont know how to simplify a problem like that then you shouldnt be doing identities like that one! 
anyhow good luck in you endeavors!

Is Dutch math like different from US/English math or something? Higher math like complex numbers, arrays and all the multidimensional stuff I've seen, but I've never heard of 'sec' or 'identity' for that matter.

crae, you are familiar with:
sin()
cos()
tan()
i presume?
there are three more operators, the "inverse" of these.
i just dint remember their names, or their exact relationships off hand
i think it is along the line of:
sec() = 1 / sin()
etc.
i never really used them, even when i was doing maths a lot in England.
craeonics - 'identity'
in this case, just a fancy word for "question" (or equation)
it would be fair to say:
the following identity is true
2 + 2 = 4
it is just that the first post had a slightly more complicated equation.

Aha. We call that an 'arcsinus' (~arc-sine) over here. Umm, no wait, no we don't... arc-sine is the inverse sine... umm... Does it show that I haven't used this in a long long time?
