im out here somewhere in the eternal ether :)

its a simple cos function.... nothing modifying it so it should be easy for us to accomplish :)

Just fyi i know NOTHING about converting thetas to square roots.

-2pi = max
- pi = min
and that all you get in that interval

I don't get it. Where are the max and min values in that? I know nothing abou this!

the cosine graph is just a wave that bounces between 1 and -1

at 0 or any even multiples of pi; cos(x) = 1
at pi or any odd multiples cos(x) = -1

nah; the max of cos(x) = 1
the min of cos(x) = -1

cos(-2pi) = 1
cos(-pi) = -1

thats just the definition for cosine...

Dx(cos(x)) = -sin(x)
-sin(x) = 0 at..... -2pi, and -pi in between [-1pi,-3pi/4]

Then "Absolute minimum is ____ at theta=____"

absolute min = -1 at -pi

absolute max = 1 at -2pi

its from trig class; trig is just memorizing angles and sin cos tan stuff

yeah, look up 'trig tables' and 'trig graphs' in google; theyll give you alot to pick from :)

i did not mean 43 hours, i meant 3

:) they will help. And when i dont use trig for a while im bound to forget them ;)

lol... i do enjoy math; its the one constant in my life :)

Good night, and thanks again.

Nite , im in florida ;)

So its like almost 4 am there!

illinois is one of them mormon states i believe

330am if the computer is right ;)

yes it is it's 2:30 here. crazy!

ttyl, thanksoncemore
