title: syntax for solving system of differential equations in sympy
body: <p>I am new to sympy and in the process of learning it. I was browsing through the documentation and questions in stack exchange regarding symbolically solving a system of differential equations with initial conditions using sympy. </p>
  
  <p>I have a simple system of ODE-s</p>
  
  <pre><code>( dV/dt )  = -(  1 / RC ) * ( V(t) ) + I(t)/C
  
  ( dI/dt )  = -( R1 /  L ) * ( I(t) ) - ( 1 / L) * V(t) + Vs/L
  </code></pre>
  
  <p>with initial conditions <code>V(0) = V0</code> and <code>I(0) = I0</code></p>
  
  <p>I browsed through a lot of questions in stack exchange and not successful in finding an appropriate answer. 
  It would be of great help if somebody can show me a syntax to enter a system of coupled differential equations with initial conditions. </p>
