... Thus, to solve for the first time step, we substitute the initial conditions for the right-hand side and solve the 22 system of equations. The best way to do this is with LU decomposition since we will have to solve the system repeatedly. For the present case, because it’s easier to display, we wil ...

nature of metacognition in a dynamic geometry
... Lester (1985), I developed a model capturing together student’s cognitive and metacognitive behaviors when problem solving in DGS (Kuzle, 2011) and their complex interplay. On the contrary to Schoenfeld (1981, 1985) the planning/implementation episodes were separated into two episodes, as they do no ...

Chapter 2: Equations, Inequalities and Problem Solving
... A car rental agency advertised renting a Buick Century for $24.95 per day and $0.29 per mile. If you rent this car for 2 days, how many whole miles can you drive on a $100 budget? 1.) Understand Read and reread the problem. Let’s propose that we drive a total of 100 miles over the 2 days. Then we ne ...

Free surface ow under gravity and surface tension due to an Applied
... Free surface flow due to an applied pressure distribution in the presence of a uniform stream has been a much-studied problem for more than a century, with applications to the forcing of water waves by atmospheric disturbances, or due to moving obstacles such as ships. For the two-dimensional flow o ...

Basis for the calculations of travel time curves in a 1D model

The next step is to identify straight lines in our plot, or in other words, slopes and intercepts. By calculating the equation of the lines we are now able to find the slopes (hence the velocities) ...
