Solving equations with one unknown through NUM.SLV

The calculator's NUM.SLV menu provides item
different types of equations in a single variable, including non-linear algebraic
and transcendental equations.
sin(πx/3) = 0.
Simply enter the expression as an algebraic object and store it into variable
EQ. The required keystrokes in ALG mode are the following:
³„¸~„x™-S„ì
*~„x/3™‚Å 0™
Function STEQ
Function STEQ, available through the command catalog, ‚N, will store
its argument into variable EQ, e.g., in ALG mode:
In RPN mode, enter the equation between apostrophes and activate command
STEQ. Thus, function STEQ can be used as a shortcut to store an expression
into variable EQ.
