# Trivial solution for cosh(x)=0 and sinh(x)=0

I'm doing Sturm-Loiuville problems and I need to find the eigenvalues for λ

I'm having difficulty understanding the trivial solutions for the hyperbolic sin and cos when they equal 0.

I know that cos(x)=0 when ##x= π/2 + πn = (2n+1)π/2##
sin(x) = 0 when ##x=πn##
