Solutions Supported by ClassPad (TRUE, FALSE, Undefined, No Solution,
∞
,
const, constn)
Solution Description Example
TRUE Output when a solution is true. judge (1 = 1)
w
FALSE Output when a solution is false. judge (1 < 0)
w
Undefined Output when a solution is undefined. 1/0
w
No Solution Output when there is no solution.

const Constant displayed as const(1) when any
value that is a constant is included in the
solution. In the case of multiple constants,
they are indicated as const(1), const(2),
and so on.

constn Constant displayed as constn(1) when the
solution includes any integer value that is
a constant. In the case of multiple
constants, they are indicated as constn(1),
constn(2), and so on.
Change the [Angle] setting to
“Degree”.
