Before getting started... k Modes Before starting a calculation, you must first enter the correct mode as indicated in the table below. • The following table shows the modes and required operations for the fx-100MS and fx-115MS.
• Mode indicators appear in the upper part of the display, except for the BASE indicators, which appear in the exponent part of the display. • Engineering symbols are automatically turned off while the calculator is the BASE Mode. • You cannot make changes to the angle unit or other display format (Disp) settings while the calculator is in the BASE Mode. • The COMP, CMPLX, SD, and REG modes can be used in combination with the angle unit settings.
• You can also edit expressions on the display and perform other multi-statement operations. For more details about using multi-statements, see “Multi-statements” in the separate “User’s Guide.” • Only the expressions in replay memory starting from the currently displayed expression and continuing to the last expression are copied. Anything before the displayed expression is not copied.
Use the formula below to calculate initial velocity A for a height of B = 14 meters and a time of C = 2 seconds. Gravitational acceleration is D = 9.8 m/s2. (Result: A = 16.8 ) B AC – (B?) (A?) (C?) (D?) (A?) 1 DC 2 2 p2pup1-pk, R1\2T-ph-pkK AI 14 = ] 2= 9l8= [[ AI • The SOLVE function finds approximations based on Newton’s method, which means that error can occur. Certain expressions or initial values may result in error without convergence of results.
• To turn engineering symbols on and off, press the F key a number of times until you reach the setup screen shown below. Disp 1 • Press 1. On the engineering symbol setting screen that appears, press the number key ( 1 or 2) that corresponds to the setting you want to use. 1(Eng ON): Engineering symbols on (indicated by “Eng” on the display) 2(Eng OFF): Engineering symbols off (no “Eng” indicator) • The following are the nine symbols that can be used when engineering symbols are turned on.
AP J Complex Number Calculations 0.9 9 ⫼1 m 900. CMPLX Use the F key to enter the CMPLX Mode when you want to perform calculations that include complex numbers. CMPLX ........................................................... F 2 • The current angle unit setting (Deg, Rad, Gra) affects CMPLX Mode calculations. You can store an expression in CALC memory while in the CMPLX Mode. • Note that you can use variables A, B, C, and M only in the CMPLX Mode.
k Absolute Value and Argument Calculation Supposing the imaginary number expressed by the rectangular form z = a + bi is represented as a point in the Gaussian plane, you can determine the absolute value (r) and argument ( ) of the complex number. The polar form is r⬔. • Example 1: To determine the absolute value (r) and argument () of 3+4i (Angle unit: Deg) (r = 5, = 53.13010235°) Imaginary axis Real axis (r 5 ) ( 53.
• You select rectangular form (a+bi) or polar form (r⬔ ) for display of complex number calculation results. F... 1(Disp) r 1(a+bi):Rectangular form 2(r⬔): Polar form (indicated by “r⬔ ” on the display) k Conjugate of a Complex Number For any complex number z where z = a+bi, its conjugate (z) is z = a – bi. • Example: To determine the conjugate of the complex number 1.23 + 2.34i (Result: 1.23 – 2.
• You can use the following logical operators between values in Base-n calculations: and (logical product), or (logical sum), xor (exclusive or), xnor (exclusive nor), Not (bitwise complement), and Neg (negation). • The following are the allowable ranges for each of the available number systems.
• Example 4: To convert the value 2210 to its binary, octal, and hexadecimal equivalents. (101102 , 268 , 1616 ) tb 0. b l l l 1(d) 22 = 10110. b Octal mode: o 26. o Hexadecimal mode: h 16. H Binary mode: • Example 5: To convert the value 51310 to its binary equivalent. tb 0. l l l 1(d) 513 = Ma t h ERROR Binary mode: b b • You may not be able to convert a value from a number system whose calculation range is greater than the calculation range of the resulting number system.
• Input a value from 1 to 4 to select the probability distribution calculation you want to perform. P(t) Q(t) R(t) • Example: To determine the normalized variate (→ t) for x = 53 and normal probability distribution P(t) for the following data: 55, 54, 51, 55, 53, 53, 54, 52 (→t = 0.284747398, P(t) = 0.38974 ) 55 S 54 S 51 S 55 S 53 S S 54 S 52 S 53 A D 4(→t) = A D 1( P( ) D 0.28 F = Differential Calculations COMP The procedure described below obtains the derivative of a function.
• You can omit input of ∆x, if you want. The calculator automatically substitutes an appropriate value for ∆x if you do not input one. • Discontinuous points and extreme changes in the value of x can cause inaccurate results and errors. Integration Calculations COMP The procedure described below obtains the definite integral of a function. Use the F key to enter the COMP Mode when you want to perform integration calculations. COMP ............................................................
Power Supply The type of battery you should use depends on the model number of your calculator. fx-115MS The TWO WAY POWER system actually has two power supplies: a solar cell and a G13 Type (LR44) button battery. Normally, calculators equipped with a solar cell alone can operate only when relatively bright light is present. The TWO WAY POWER system, however, lets you continue to use the calculator as long as there is enough light to read the display.
fx-100MS This calculator is powered by a single AA-size battery. • Replacing the Battery Dim figures on the display of the calculator indicate that battery power is low. Continued use of the calculator when the battery is low can result in improper operation. Replace the battery as soon as possible when display figures become dim. • To replace the battery 1 Press A i to turn power off. Screw 2 Remove the six screws that hold the back cover in place and then remove the back cover.
