      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.

     Differential Calculations Press                to enter COMP mode.
      To perform a differential calculation, you have to input the  expression in the form of: 
                                     differential expression        a           x 
    •  The differential expression must contain the variable x.
    •  "a" is the differential coefficient. 
    •  "   x" is the change interval of x (calculation precision).
    Example: To determine the derivative at point x = 10,    x = 10
    -8, for 
    the function f(x) = sin(3x + 30). 
    Example: For the equation Y = 5x
    2 –2x +1, calculate the value of Y if 
    x = 5 or x = 7. 
    !  The         stored expression will be cleared when you start a new  calculation, change into another mode, or turn off the calculator.

     Integration Calculations Press               to enter COMP mode.
      To perform an integration calculation you are required to input the  following elements:
                              integration expression       a       b       n  
    •  The integration  expression has a variable x.
    •  "a" and "b" defines the integration range of the definite integral. 
    •  "n" is the number of partitions (equivalent to N = 2
    n). 
      The integration calculation is based on Simpson’s rule.
    As the number of significant digits is increased, internal integration 
    calculations may take considerable time to complete. For some 
    cases, even after considerable time is spent performing a 
    calculation, the calculation results may be erroneous. Particularly 
    when significant digits are less than 1, an ERROR might occur.
    Example: Perform the integration calculation for , with n = 4.
    !  You can leave out the    x in the differential expression and the 
    calculator will automatically substitute a value for    x.
    !  The smaller the entered value    x is, the the longer the calculation  time will be with more accurate results, the larger the entered value     
         x is, the shorter the calculation time will be with comparatively  less accurate results.
    !  Discontinuous points and extreme changes in the value of x can  cause inaccurate results or errors.
    !  When performing differential calculations with trigonometric  functions, select radian (Rad) as the angle unit setting.
    ! Log
    ab, i~Rand, Rec ( and Pol ( functions can not join to differential
