The `d M` (`calc-mathematica-language`

) command selects the
conventions of Mathematica. Notable differences in Mathematica mode
are that the names of built-in functions are capitalized, and function
calls use square brackets instead of parentheses. Thus the Calc
formula ‘`sin(2 x)`’ is entered and displayed ‘`Sin[2 x]`’ in
Mathematica mode.

Vectors and matrices use curly braces in Mathematica. Complex numbers
are written ‘`3 + 4 I`’. The standard special constants in Calc are
written `Pi`

, `E`

, `I`

, `GoldenRatio`

, `EulerGamma`

,
`Infinity`

, `ComplexInfinity`

, and `Indeterminate`

in
Mathematica mode.
Non-decimal numbers are written, e.g., ‘`16^^7fff`’. Floating-point
numbers in scientific notation are written ‘`1.23*10.^3`’.
Subscripts use double square brackets: ‘`a[[i]]`’.
