Solve Function

■
Solve functions use Newton's Method to obtain the approximate
solution of equations.
Note: SOLVE function can be used in the COMP Mode only.
■
The following describes the types of equations whose solutions
can be obtained by using SOLVE function.
•
Equations that include variable X,
SOLVE function solves for X, for example, X
X – 5 = A + B, X = tan(C),
•
Variable X to be solved should be put at the left hand side of
the equation.
For example, an equation is input as X
or X 2 + 5X – 24
•
An expression like X
not necessary to input "= 0".
•
Equations input uses the following syntax :
{equation},{solution variable}
In general, an equation is solved for X, unless specified. For
example, to solve for Y when an equation is input as, Y = X + 5, Y
2 + bx + c = 0 (a second-order polynomial
equation with a single variable x)
: ax 3 + bx 2 + cx + d = 0 (an equation with cubic
polynomial)
: ax 4 + bx 3 + cx 2
2 + 5X – 24 will be treated as X
