Using SOLVE

SOLVE uses Newton’s Law to approximate the solution of equations. Note that SOLVE can be used in the COMP Mode (N1) only.

The following describes the types of equations whose solutions can be obtained using SOLVE.

•Equations that include variable X: X2 + 2X – 2, Y = X + 5, X = sin(M), X + 3 = B + C

SOLVE solves for X. An expression like X2 + 2X – 2 is treated as X2 + 2X

– 2 = 0.

•Equations input using the following syntax: {equation}, {solution variable}

SOLVE solves for Y, for example, when an equation is input as: Y = X + 5,

Y

Important: • If an equation contains input functions that include an open parenthesis (such as sin and log), do not omit the closing parenthesis.

•The following functions are not allowed inside of an equation: ∫, d/dx, Σ,

Π, Pol, Rec, ÷R.
