Question

obtain the general solution of auxiliary equation y'' - 8y' + 17y =0 y(0)=4 y'(0)=-1

Answer 1

didnt i answer this? where is my work

Answer 2

Lol

Answer 3

You can solve this using basic algebra techniques.

Answer 4

hmmm, its a homogenous differential equation

Answer 5

the characteristic equation gave us two roots, 4+i, 4 - i

Answer 6

pangji, please post my work i did earlier. i am discouraged by this

Answer 7

the general solution. this is a relatively easy problem to explain. you should just explain it again for him/ her :)

Answer 8

the general solution was
y = e^(4x) ( c1 * cos x + c2 * sin x )

Answer 9

yep. and now what's next :)

Answer 10

plug in zero, take the derivative, etc

Answer 11

Don't tell me, tell the asker :)

Answer 12

oh they left
