WebApr 25, 2014 · Step 1 You have a quadratic graph with complex roots, say y = (x – 1) 2 + 4. Written in this form we can see the minimum point of the graph is at (1,4) so it doesn’t cross the x axis. Step 2 Reflect this graph downwards at the point of its vertex. We do this by transforming y = (x – 1) 2 + 4 into y = - (x – 1) 2 + 4 Step 3 WebThe complex components in the solution to differential equations produce fixed regular cycles. Arbitrage reactions in economics and finance imply that these cycles cannot persist, so this kind of equation and its solution are not really relevant in economics and finance.
