It can be helpful to verbalize exactly what we’re solving for. Altogether, these terms are equal to G ( x ) G(x) G ( x ), another function of x x x. Each term on the left-hand side of the equation has one of these functions of x x x as its coefficient. We can call this equation linear because each of these functions is a function of x x x only. P ( x ) P(x) P ( x ), Q ( x ) Q(x) Q ( x ), and R ( x ) R(x) R ( x ) are each functions of x x x. Y ’ y’ y ’ indicates the first derivative of y y y with respect to x x x Y ’’ y’’ y ’’ indicates the second derivative of y y y with respect to x x x Please see the TI-89 family, TI-92 family and Voyage 200 guidebooks for additional information.P ( x ) y ’’ + Q ( x ) y ’ + R ( x ) y = G ( x ) P(x)y’’ + Q(x)y’ + R(x)y = G(x) P ( x ) y ’’ + Q ( x ) y ’ + R ( x ) y = G ( x ) Note: The TI-89 Family, TI-92 Plus and Voyage 200 can solve the following types of 1st and 2nd order differential equations:ġst Order: separable, linear, Bernoulli, y'=f(a*x+b*y), exact, integrating factor independent of x, integrating factor independent of y, and homogeneous.Ģnd Order: linear constant coefficient (and a few variable coefficient), missing y, missing y', missing x, missing both y' and x. After inputting the final equation type.Input the remaining equations separated by ' and'.Choose ' and' from the list and press.Solve the second order differential equation below to model the height of the ball over time: Second Order Example: A ball is tossed straight up from an initial height of 0.29 meters and with an initial velocity of 3.8m/s.
