Differential Equations on the TI-89 Change mode from 1: Function to 6: Diff Equations Go to the y= editor and press [Diamond/Yellow] and [|] Make sure “Solution Method” is Euler Make sure “Fields” is SLFLD Go to the y= editor and enter your derivative In y1’: Use [t] instead of [x] and use [y]1 (type y and a 1) instead of [y] In y2’: Use [t] instead of [x] and use [y]2 (type y and a 2) instead of [y] Drawing a solution curve through an initial condition: Set “t0” equal to the x (or t) coordinate of the initial condition

Unformatted text preview: • Set “yi1” equal to the y coordinate of the initial condition Using Euler’s Method: • Set up the y= editor the same way as for the solution curve method (we’re actually using Euler’s Method to draw the solution curve) • In the Window screen set t0 equal to the initial x value (tmax doesn’t really matter so long as it is larger than the x value of the point on the curve you are trying to approximate) • Set the tstep equal to the step size • Graph and trace. The calculator tells you tc, xc, and yc....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
