"WebLet’s see how the shooting methods works using the second-order ODE given f ( a) = f a and f ( b) = f b. Step 1: We start the whole process by guessing f ′ ( a) = α, together with f ( a) = f a, we turn the above problem into an initial value problem with two conditions all on value x = a. This is the aim step. Step 2: Using what we learned ... " - Bisection scipy
