The first one, the proffesor gave us a hint and I do that...but these two I have no idea how to start... http://img89.imageshack.us/img89/9218/23yn8.png I will really apreciate if anyone can tell me something, maybe just how to started it or what should I use, I tried to find some...

Hi! I want to know if I do correctly this exercise!? http://img232.imageshack.us/img232/4857/calculo1ui2.png I am in stress because of this class! Me está volviendo loca!

Thanks! F(\theta) = p (sen\theta/cos^{1-p}) - sen(p\theta) > 0 ...however ... cos (p\theta) > cos (\theta)^{p} F'(\theta) = p (sen\theta/cos^{1-p} - sen p (\theta) > 0 (positive) We did it...?

F(\theta) = cos (\theta) p- cos (p\theta) How I use this? iah...I don't Know... F(theta) = cos (theta)p- cos (p(theta))

ok thanks... I will try! jeje...I have one hour to think !

i know how to used the binomial theorem, but i don't know how to used it with taylor's polynomial i don't even know what that is..

i don't know how to used it, explain me please!

:biggrin: jeje thanks . . . I'm friend of medinap...we really need help with this exercise! First the professor...gave us (cos\theta)p\leq cos(p\theta) but he don't gave us the values of p (we asume that n is for all natural p=2(2n+1)...but yesterday! he made a correction that 0< p< 1...

a doubt come into my mind when i was doing the calculus exercise. ...i need to know if in the fresnel integral i can used any limit of integration or only from 0 to infinite...:confused:

THANK YOU!o:):cool:

iah...very ugly...wow! thanks thanks... jeje now I will try to understand it!

thanks... sorry for my english...I hope that can understand me... This integral \int_{1} ^{\infty} cos(x)cos(x2) dx I have to say that is convergent or divergent. The proffessor gave us a hint (Fresnel Integral)...but I don't know how to use it, He don't...

cos(x)cos(x^2)

I need help for this integral cosx cosx^{2}
