Question 4 The most commonly used method for solving ordinary differential equations is... O Euler O 2nd-order Runge-Kutta O 6th-order Runge-Kutta 4th-order Runge-Kutta O Verlet O Leapfrog Question 5 Check all that are true about the Lorenz Equations. They are an example of chaos. They are a set of interdependent differential equations. O They are an example of control. They exhibit the butterfly plot. O They specify time and length dilationQuestion 6 Partial differential equations are solved using: () other methods as they are not solvable using Python @ any of a number of available packages () iterative methods without any available package () the pdeint function Question 7 One of the problems in selving partial differential equations has to do with the grid size Check all of the reasons this is the case. Too many points can require too much computation 0dd shapes mean spacing can vary Finding the right grid size can be guesswork Question 8 The solution to a partial differential equation, if it exists, can always be found using overrelaxation. () True @ False Question 9 The solution to a partial differential equation, if it exists, can always be found using the Gauss-Seidel method. () True @ False
