Subject: [PATCH] limits of fresnel_c and fresnel_s

Hello,
I am attaching a patch for the limits of fresnel_c
and fresnel_s.
Also, we have
(%i14) diff(fresnel_c(x),x);
(%o14) cos(%pi*x^2/2)
(%i15) diff(fresnel_s(x),x);
(%o15) sin(%pi*x^2/2)
But integrating cos(x^2) and sin(x^2) give complicated expressions,
when they should probably return the fresnel integrals... unless there
is a switch I don't know about.
Tracing gives this:
1: (DIFFDIV ((%COS SIMP) ((MEXPT SIMP) $X 2)) $X)
1: DIFFDIV returned NIL
