initial conditions

Consider ordinary differential equations given by ẋ₁(t) = 2x₂(t) ẋ₂(t) = r(t) with initial conditions x₁(0) = 1 and x₂(0) = 0. If r(t) = {1, t ≥ 0; 0, t < 0}, then at t = 1, x₁(t)...

A unit step voltage is applied at $$t = 0$$ to a series $$RL$$ circuit with zero initial conditions.
