(1) x 1 ∂ 1 f + x 2 ∂ 2 f = f + λ ( x 1 + x 2) together with initial condition f ( x 1, g ( x 1)) = ψ ( x 1) along some curve in the x 1, x 2 plane which is the graph of x 2 = g ( x 1). The function is often thought of as an unknown to be solved for, similarly to how x is thought of as an unknown number to be solved for in an algebraic equation like x2 − 3x + 2 = 0.
