Solving equations with one unknown through NUM.SLV 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(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™,Å0™ K~e~q` Function STEQ 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. Press J to see the newly created EQ variable: Then, enter the SOLVE environment and select Solve equation..., by using: ,Ï@@OK@@. The corresponding screen will be shown as: Page 6-9
