Unformatted text preview: WeBWorK assignment number HW21 is due : 02/28/2010 at 06:06am PST. Online lecture Go to class web page and replace the end of the internet address teaching34BW10.html by 34BL17 for lecture 17 etc. 1. (1 pt) Cooper 13.9.1 Use Eulers method with t = . 1 for the equation y = y with initial condition y ( ) = 1. Go to page 230. Fill in the gaps on table 13.2 below: t = 0.3: Eulers method: , Percentage error: %. t = 0.6: Eulers method: , Percentage error: %. t = 0.9: Eulers method: , Percentage error: %. 2. (1 pt) Cooper 13.9.2 Use two steps of Eulers method with t = . 2 for the equa- tion y = y- t with initial condition y ( ) = 1. y ( . 4 ) = 3. (1 pt) Cooper 13.9.3 Use Eulers method to find y ( . 4 ) if y = 1- y 2 and y ( ) = . 5. Use a timestep of 0.1. y ( . 4 ) = . 5. (1 pt) Cooper 13.9.6 Describe how to modify Eulers method to deal with the ini- tial condition of y ( 5 ) = 3 instead of y ( ) = 3....
