(COMP MODE)
(radius is B=5cm)
(height is C=2cm)
(Calculate with new variables)
Solve Function
You can solve custom calculation expressions in COMP mode.
Simply input the expression with different variables and press the
key.
Solves for X, for example, when an equation is input as:
X = Y + 5, X
Solves for Y, for example, when an equation is input as:
Y = X + 5, Y
Example: A cone with height "h' and a circular base with radius "r";
find the cone volume using this formula:
Replace the variable "V" with X, variable "r"
with "B", and variable "h" with "C".
CALC Function
CALC function is a memory zone with a maximum of 79
steps to store a single calculation expression which can be
recalled and calculated a number of times with different
values.
After inputting the calculation expression and pressing ,
the calculator will request for the current value of your input
variables.
CALC function can only be used in COMP mode or CPLX
mode.
! If the expression does not include the equal sign ( = ) when
Solve calculation is performed, the calculator will transform
the solution as zero ( 0 ).
! Solve function cannot be solved an equation.
! When the expression cannot be solved, [Can’t Solve] will be
displayed.
