Question Number 156086 by MathSh last updated on 07/Oct/21
ψ^((1)) ((1/6)) - ψ^((1)) ((5/6)) = 10ψ^((1)) ((1/3)) - ((20)/3)π^2
ψ(1)(16)ψ(1)(56)=10ψ(1)(13)203π2

ψ^((1)) ((1/6))−ψ^((1)) ((5/6))=π^2 (1+cotan^2 ((π/6)))  =π^2 +π^2 cotan^2 ((π/6))  tan^2 ((π/6))=((sin^2 (π/6))/(cos^2 (π/6)))=(1/4)×(4/( 3))=(1/3)  ⇒ π^2 +π^2 cotan^2 (π/6)=π^2 (1+(1/3))=((4π^2 )/3)...
ψ(1)(16)ψ(1)(56)=π2(1+cotan2(π6))=π2+π2cotan2(π6)tan2(π6)=sin2π6cos2π6=14×43=13π2+π2cotan2π6=π2(1+13)=4π23

Mr tabata we have :   ψ^((1)) (x)−ψ^((1)) (1−x)=π^2 (1+cotan^2 (πx))
Mrtabatawehave:ψ(1)(x)ψ(1)(1x)=π2(1+cotan2(πx))
