Nanie said:cos(x)cos(x^2)
Nanie said:thanks... sorry for my english...I hope that can understand me...
This integral [tex]
\int_{1}[/tex] [tex]^{\infty}[/tex] 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 discuss it in class :grumpy:. I understand everything but the cos(x2) jeje I don't know how to integrate.:yuck:
Thanks gabbagabbahey for the link...
medinap said:im nanies roommate and we take the class together and the problem is that i don't understand what u did in the first part of this problem and don't know where the cosX^2 - X come from. also i don't understand why u divided everything by 2...please help me
Nanie said: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...
The cosx cosx integral, also known as the double cosine integral, is an indefinite integral that involves the product of two cosine functions. It is represented by the equation ∫cosx cosx dx.
To solve the cosx cosx integral, you can use the trigonometric identity cosx cosx = 1/2(cos2x + 1). This will transform the integral into the form ∫1/2(cos2x + 1) dx, which can then be solved using integration by substitution or integration by parts.
No, a calculator cannot solve the cosx cosx integral as it involves integration, which is a mathematical process that cannot be performed by a calculator. You will need to use integration techniques to solve this integral.
The domain of the cosx cosx integral is all real numbers. This means that the integral can be evaluated for any value of x within the real number system.
The cosx cosx integral is important in science as it is commonly used in physics and engineering to solve problems involving waves and oscillations. It is also used in signal processing and electrical engineering to analyze and manipulate signals. Understanding how to solve this integral is crucial in these fields of study.
