Notethat SOLVE can be used in the COMP Mode (N1) only.The following describes the types of equations whose solutions can beobtained using SOLVE.• Equations that include variable X: X2 + 2X – 2, Y = X + 5, X = sin(M), X+ 3 = B + CSOLVE solves for X. An expression like X 2 + 2X – 2 is treated as X2 + 2X– 2 = 0.• Equations input using the following syntax: {equation}, {solutionvariable}SOLVE solves for Y, for example, when an equation is input as: Y = X + 5,YImportant: • If an equation contains input functions that include an openparenthesis (such as sin and log), do not omit the closing parenthesis.• The following functions are not allowed inside of an equation: ∫ , d /dx, Σ ,Pol, Rec.To solve y = ax2 + b for x when y = 0, a = 1, and b = –2Sf(Y) Ss(=)S-(A)S)(X) w+Se(B)1s(SOLVE)Prompts for input of a value for Y Current value of YMathMathMathCMPLX MathCMPLXMathMathMathMath
