Example
For a general solution, use the following syntax. For a particular solution, refer to the
Technical Reference module.
deSolve(1stOr2ndOrderODE, independentVar, dependentVar)
Using the logistic 1st-order differential equation, find the general solution for y with
respect to t.
Notes:
• For maximum accuracy, use 1/1000 instead of .001. A floating-point number can
introduce round-off errors.
• This example does not involve graphing, so you can use any Graph mode.
deSolve(y' = 1/1000 yù(100Ny),t,y)
Do not use implied multiplication between the
variable and parentheses. If you do, it will be
treated as a function call.
