Finally R(t)=R(o)exp(-λt) where R(0)=exp(C). File Format: PDF/Adobe Acrobat - Quick View simulations and numerical methods are useful. We came to the section where we learn to solve high order linear differential equations with constant coefficients. Flip PointedArray a) (range $ bounds a))). Faculty.olin.edu/bstorey/Notes/DiffEq.pdf. We went over the characteristic polynomial, and the case where it has a repeated root. Differential equations - easy to hear but often impossible to solve- are around there in our life. The interest rate — 5% seems a bit high these days r = 0.05. Now let's set up the parameters for our equation. Our memory can be expressed by the first-order autonomous differential equation. Then we need to solve the Black-Scholes equation: We can approximate the partial differential equation by a difference equation (the minus sign on the left hand side is because we are stepping backwards in time): (PointedArray i a) = a!i ( PointedArray i a) =>> f = PointedArray i (listArray (bounds a) (map (f . Let me show you Note that dlnR(t)/dR(t) = 1/R(t). If you are an econ learner, The differential equations that are used to express them could usually be relatively easy to solve. ..(5) Note that R(t) = exp(-λt+C).
