#### Integration_constant

-- System variable: integration_constant Default value: `%c`

When a constant of integration is introduced by indefinite integration of an equation, the name of the constant is constructed by concatenating `integration_constant` and `integration_constant_counter`.

`integration_constant` may be assigned any symbol.

Examples:

```          (%i1) integrate (x^2 = 1, x);
3
x
(%o1)                     -- = x + %c1
3
(%i2) integration_constant : k;
(%o2)                           k
(%i3) integrate (x^2 = 1, x);
3
x
(%o3)                      -- = x + k2
3```

There are also some inexact matches for `integration_constant`. Try `?? integration_constant` to see them.

```(%o1)                                true
(%i2) ```
