Examples

Basic Examples  (1)

An error occurs because the limits on the independent variable do not have values:

Wolfram Language code: NDSolve[{f'[t] == f[t], f[1] == 1}, f, {t, t1, t2}]

This shows a correct specification of the limits on the variable:

Wolfram Language code: Block[{t1 = 1, t2 = 2}, NDSolve[{f'[t] == f[t], f[1] == 1}, f, {t, t1, t2}]]
