## Homework Statement

Find the solution of the equation

v''- 4v'+5v=0,such that v=-1 and v'=1 when x=pi=3.14159

## Homework Equations

........

## The Attempt at a Solution

I treat it as a polynomial=>r^2+4r+5=0

=>delta=-4=>r1=2+2i and r2=2-2i

v=e^[x+2](A*cos[2]+B*i*sin[2])

v=-1=e^[pi+2](A*cos[2]+B*i*sin[2])

v'=0....so I"m stuck and I need some help
