The complete question is

"Find the general solution of the given differential equation

y''-y=0, y1(t)=e^t , y2(t)=cosht

The function [tex]y(t)=e^t[/tex]  is the solution of the given differential equation.

The function y(t)=cosht is the solution of given differential equation.

What is a function?

The function is a type of relation, or rule, that maps one input to specific single output.

Given;

[tex]y_1(t) = e^t[/tex]

Given differential equations are,

y''-y = 0

 So that,  

[tex]y' (t) = e^t, y'' (t) = e^t[/tex]

Substitute values in the given differential equation.

[tex]e^t -e^t=0[/tex]

                   

Therefore, the function [tex]y(t)=e^t[/tex]  is the solution of the given differential equation.

Another function;

[tex]y(t)=cosht[/tex]  

So that,  

[tex]y"(t)=sinht\\\\y"(t)=cosht[/tex]

Hence, function y(t)=cosht is solution of given differential equation.
