Solving equations with one unknown through
The calculator's NUM.SLV menu provides item 1. Solve equation.. solve
different types of equations in a single variable, including non-linear
algebraic and transcendental equations.
For example, let's solve the
equation: ex-sin( x/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:
Function STEQ 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.
