Question

Solve to have a general Solutions and then apply Boundary Please this time someone who can explain

Answer 1

\[\frac{ d^2y }{ dx^2 }+y=0\]
Boundaries are
\[y(0)=1\]
And \[y'(\frac{ \pi }{ 2 })= -1\]

Answer 2

what technique were you taught to solve this type problem ?

Answer 3

Separation variable method for general solution

Answer 4

Coefficient , comparison and substitute method for boundaries

Answer 5

how far did you get ?

Answer 6

ok, but I would flip both sides
