I'll ask you some question.you make score for yourself with answering right.and also you can ask your questions here.
1.If X-->0 then Lim (2x-sinx)/(2x+sinx)=?
1)1 2)1/2 3)1/3 4)0
2.If f`(x)=1/x y`=f(5x)=?
1)1 2)1/x 3)2x 4)0

(sin theta / 1 + cos theta) + [(1 + cos theta)/ sin theta]

Anyone know how I can get that to 2 cosec theta?

Ah, good old trigonometry. Killed my GPA back in high school.

This looks like homework help, not general discussion.
Where's the value in this thread?

i was wondering that, my original post was going to be "stop making us do your homework"

or words to that effect.

Don't worry,It's not my homework,I passed this last year.Just for realize your IQ.;)
Anyway:
answer 1 : lim (2x-sinx)/(2x+sinx) = lim x(2- (sinx/x))/x(2+(sinx/x)) = (2-1)/(2+1) =1/3
so Question 1: 3
answer 2 : y`=5f`(5x)=5(1/5x)=1/x
so Question 2: 2
I realized your IQ.:D

And another one:
If f(x): (x+1).h(x)/(2x+1).h(2x+1) f(-1)=?
1)1/x 2)-1 3)3 4)2x

You can't find someone's IQ just by asking these questions.

i always find that the question "What's your IQ?" gives better results

It's best way.And it shows your sub-zero IQ.;):D
Don't change the topic when you cann't answer this questions.

So you're implying that people that aren't interested in math and/or don't have a talent for math are stupid?? I know a lot of people much smarter than you that don't know shit about math.
