Fresnel Integral

[LCieParagon]

Hello. I have a question.

Is there any plans to implement the Fresnel Integral into the HP Calculator?

For example, when I try to compute:
integral(cos(x^2),x,0,t) I get rather strange results.
For instance, if I choose t to be 2, I receive 0.46146...
If I choose t to be 1000, I receive a 1x2 vector: [-1.9805..., 10.78289...]
Clearly, a definite integral is not a 1x2 vector, it is in fact a number.

Moreover, if t approaches infinity, the value should be (1/2) * sqrt(pi/2). I receive a 1x2 vector again.

If I could have any help on the matter, I'd appreciate it. Thanks.
