[. . . ] The alternate function is indicated by the text printed above the key. Alternate function sin­1{D} Keycap function s · The following shows what the different colors of the alternate function key text mean. If key marking text is this color: Yellow Red Purple (or enclosed in purple brackets) Green (or enclosed in green brackets) It means this: Press 1 and then the key to access the applicable function. Press S and then the key to input the applicable variable, constant, or symbol. Enter the BASE-N Mode to access the function. · The following shows an example of how an alternate function operation is represented in this User's Guide. [. . . ] Note that you must input the base (base m) when using the & key for input. Appendix <#023> to <#025> *1 A base of 10 (common logarithm) is used if no base is specified. E-33 k Power Functions and Power Root Functions · Power functions and power root functions can be used in the COMP, STAT, EQN, MATRIX, TABLE, and VECTOR calculation modes. · The X2 , X3 , X­1 functions can be used in complex number calculations in the CMPLX Mode, and complex number arguments are supported. · The X^, '(, 3'(, ^'( functions can be used in the CMPLX Mode, as long as complex numbers are not used as their arguments. Appendix <#026> to <#030> k Integration Calculations This calculator performs integration using the Gauss-Kronrod method of numerical integration. ( f(x), a, b, tol ) f(x): Function of X (All non-X variables are treated as constants. ) a: Integration interval lower limit b: Integration interval upper limit tol: Tolerance range (input/output format: Linear) · You can omit specification of the tolerance range. · (, d/dx(, Pol(, Rec(, and ( cannot be used within f(x), a, b, or tol. · Integration calculations can be performed in the COMP Mode only. · The integration result will be negative when f(x) < 0 within an integration interval that conforms with a < x < b. Example: (0. 5X2 ­ 2, ­2, 2) = ­5. 333333333 · A "Time Out" error occurs when an integration calculation ends without the ending condition being fulfilled. · When performing an integration calculation involving trigonometric functions, specify Rad as the calculator's default angle unit. !, Abs(, Ran#, nPr, nCr, Rnd( · These functions can be used in the same modes as the trigonometric functions. In addition, the Abs( and Rnd( functions can be used in complex number calculations in the CMPLX Mode. Factorial (!) This function obtains the factorials of a value that is zero or a positive integer. = 40320 Absolute Value Calculation (Abs) When you are performing a real number calculation, this function simply obtains the absolute value. Appendix <#039> Abs (2 ­ 7) = 5 Random Number (Ran#) This function generates a 3-digit pseudo random number that is less than 1. The random 3 digit decimal values are converted to 3-digit integer values by multiplying by 1000. Values actually generated by your calculator will be different. Permutation (nPr) and Combination (nCr) These functions make it possible to perform permutation and combination calculations. n and r must be integers in the range of 0 < r < n < 1 × 1010. Appendix <#041> How many four-person permutations and combinations are possible for a group of 10 people? E-38 Rounding Function (Rnd) This function rounds the value or the result of the expression in the function's argument to the number of significant digits specified by the number of display digits setting. Display Digits Setting: Norm1 or Norm2 The mantissa is rounded to 10 digits. Display Digits Setting: Fix or Sci The value is rounded to the specified number of digits. Example: 200 ÷ 7 × 14 = 400 LINE 200/7*14= (Specifies three decimal places. ) 1N6(Fix)3 FIX (Calculation is performed internally using 15 digits. ) FIX 200/7= FIX *14= The following performs the same calculation with rounding. FIX 200/7= (Round the value to the specified number of digits. ) FIX 10(Rnd)= (Check rounded result. ) FIX *14= E-39 k Practical Examples Appendix <#042> 0(sinX + cosX ) dX = 2 (tol: Not specified) <#043> Confirm that the two sides of the following equation are equal: e= 1 n=0 n! Transforming Displayed Values You can use the procedures in this section to transform a displayed value to engineering notation, or to transform between standard form and decimal form. k Using Engineering Notation A simple key operation transforms a displayed value to engineering notation. [. . . ] · The calculation you are performing has caused the capacity of the matrix stack to be exceeded. · The calculation you are performing has caused the capacity of the vector stack to be exceeded. · Action · Simplify the calculation expression so it does not exceed the capacity of the stack. · Try splitting the calculation into two or more parts. Syntax ERROR · Cause · There is a problem with the format of the calculation you are performing. [. . . ]
