    Differential Equations, where did I go wrong?
    \frac{dy}{dt}=-10y

    -10\int \:\frac{1}{y}dy=\int dt\:

    -10lny=t+c\: when y=1000 and t=0 c=-10ln(1000)

    -10lny=t-10ln(1000)\:

    -10lny+10ln\left(1000\right)=t

    10t(-lny+ln1000\right)=t

    \:10[ln(\frac{1000}{y})]=t\:

    ln(\frac{1000}{y})=\frac{t}{10}

    \frac{1000}{y}=e^{\frac{t}{10}}

    \:y=\frac{1000}{e^{\frac{t}{10}}  }

    The Answer is y=1000e^{-10t}

    The maths forum doesn't work properly using the app You can always switch to the mobile site to view the maths formatting properly.
