$f(x)=-x$ and initial condition $x(0)=1$

Using the Euler Method with the step size $\Delta t=1$, estimate $x(1)$ numerically.

I so far did:

$X_{n+1} = X_n+f(x_n)(1) $

$X_1=0$

$X_2=0 $

I have a similar question on my test tomorrow. Any help will be appreciated

    Try using a different value for $\Delta t$.2012-10-31

    use $h=\Delta t = 0.1$2012-10-31

    @F'OlaYinka: but the question specifically asked for $\Delta t=1$2012-10-31

    Actually, wait a second; where's the differential equation?2012-10-31

    @EdGorcenski I was just wondering the same thing.2012-10-31
