§12.12 Integrals

12.12.1 0e-14t2tμ-1U(a,t)dt=π2-12(μ+a+12)Γ(μ)Γ(12(μ+a+32)),
μ>0 ,
12.12.2 0e-34t2t-a-32U(a,t)dt=214+12aΓ(-a-12)cos((14a+18)π),
a<-12,
12.12.3 0e-14t2t-a-12(x2+t2)-1U(a,t)dt=π/2Γ(12-a)x-a-32e14x2U(-a,x),
a<12,x>0.

Nicholson-type Integral

12.12.4 (U(a,z))2+(U¯(a,z))2=232πΓ(12-a)0e2at+12z2tanhtsinh(2t)dt,
a<12 .

When z (=x) is real the left-hand side equals (F(a,x))2; compare (12.2.22).

For further integrals see §§13.10, 13.23, and use (12.7.14).
