SIGNTAB
CAS: Tabulate the sign of a rational function of the current CAS variable.
SIMP2
CAS: Simplify two objects by dividing them by their greatest common divisor.
SIMPLIFY
CAS: Simplify an expression.
SIN
Type: Analytic function
Description: Sine Analytic Function: Returns the sine of the argument.
For real arguments, the current angle mode determines the number
's units, unless angular units
are specified.
For complex arguments, sin(x + iy) = sinx coshy + i cosx sinhy.
If the argument for SIN is a unit object, then the specified angular unit overrides the angle mode
to determine the result. Integration and differentiation, on the other hand, always observe the
angle mode. Therefore, to correctly integrate or differentiate expressions containing SIN with a
unit object, the angle mode must be set to radians (since this is a “neutral” mode).
