50 39 LINE MODE: (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. Display Key in operation 0 X=(1 _|3) B2C 0 B? 0 C? 0 Solve for X 0 X=(1 _|3) B2C X= 523.5987756 L -R = 0 Radius is 5cm, cone height is 20cm, calculate the cone volume.
51 40 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.

52 41 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 calculations. Display Key in operation 0 236 (5X^(4)+3X2+2X n=2n, 1 n 9, n 0
