Odd Function Problem

[Martingale]

31. Write as a single equation in x and y: x = t + 1, y =

solve for and plug the expression for into

34. Express x in terms of the other variables in this picture: http://www.flickr.com/photos/46210274@N07/4918073428/ (I drew it myself, I know it's kind of small, but it is a replica of the drawings in the packet)

Use the properties of similar triangles.

Oh, okay, well, what are the properties of similar triangles, or where can I find them here on Purplemath?

And thank you for answering all of my other questions, I'm pretty much done with the packet after these!

Hint: For pairs of similar figures, the pairs of corresponding sides are proportional.

Oh, alright! I thought that would just be too simple to work. >< When I get to this one, I'll return with the finished product!

Your title to this thread through me off a little... you know that there are function that are Odd Functions.

So 2x+3 is not and odd function

Oh, I'm sorry, I didn't mean to throw you off. I was aware of the existence of odd functions, but this one is odd as in strange, or different.

Okay, I've got another one from question 31. It's letter c, and as before, I'm supposed to write it as one equation, but this one involves sine and cosine:

x=sin t
y=cos t

I need some help here. What I did was:

t = arcsin x

y = cos (arcsin x)

But that can't be right, and if it is, I don't know how to complete it.

One way ....

we know

so replace with

and solve for

[burnbird16]

But that's what I had originally, and I can't solve for y. Please, explain.
