E-13 COMP Differ ential Calculations The procedure described below obtains the derivative of a function. Use the F key to enter the COMP Mode when you want to perform a calculation involving differentials. COMP ........................................
E-14 COMP •Y ou can omit input of ∆ x , if you want. The calculator automatically substitutes an appropriate value for ∆ x if you do not input one. •D iscontinuous points and extreme changes in the value of x can cause inaccurate results and errors.
E-15 k Creating a Matrix To create a matrix, press A j 1 (Dim), specify a matrix name (A, B, or C), and then specify the dimensions (number of rows and number of columns) of the matrix. Next, follow the prompts that appear to input values that make up the elements of the matrix.
E-16 k Editing the Elements of a Matrix Press A j 2 (Edit) and then specify the name (A, B, or C) of the matrix you want to edit to display a screen for editing the elements of the matrix. k Matrix Addition, Subtraction, and Multiplication Use the procedures described below to add, subtract, and multiply matrices.
E-17 (M atrix C 2 2) A j 1 (Dim) 3 (C) 2 = 2 = (E lement input) 2 = D 1 = D 5 = 3 = t (3 MatC) 3 - A j 3 (Mat) 3 (C) = k Obtaining the Determinant of a Matrix Y ou can use the procedure below to determine the determinant of a square matrix.

E-19 Use the F key to enter the VCT Mode when you want to perform vector calculations. VCT ..................................................... F F F 3 Note that you must create one or more vector before you can perform vector calculations. •Y ou can have up to three vectors, named A, B, and C, in memory at one time.
E-20 • Example: To add V ector A = (1 – 2 3) to V ector B = (4 5 –6 ). (Result: (5 3 –3) ) ( 3-dimensional V ector A) A z 1 (Dim) 1 (A) 3 = (E lement input) 1 = D 2 = 3 = t ( 3-dimensional V e.
E-21 k Calculating the Outer Product of T wo V ectors Use the procedure described below to obtain the outer product for two vectors. • Example: To c a lculate the outer product of V ector A and Ve c.
E-22 COMP (Ans (AbsVctA AbsVctB)) R A A A z 3 (Vct) 1 (A) - A A A z 3 (Vct) 2 (B) T = (cos –1 Ans) (Result: 108.4349488 ° ) A V g = (VctA VctB) A z 3 (Vct) 1 (A) - A z 3 (Vct) 2 (B) = (AbsVctAns) A A A z 3 (Vct) 4 (Ans) = (VctAns Ans) (Result: (– 0.
E-23 COMP u Conversion Pair T able Based on NIST Special Publication 81 1 (1995). Scientific Constants Use the F key to enter the COMP Mode when you want to perform calculations using scientific constants. COMP ........................................
E-24 •S imply input the number that corresponds to the scientific constant you want to look up and it appears instantly on the display . • See the Scientific Constant T able for a complete list of available constants. • Example: To determine how much total energy a person weighing 65kg has (E = mc 2 = 5.
E-25 To select this constant: Input this scientific constant number: molar volume of ideal gas (Vm) 26 molar gas constant (R) 27 speed of light in vacuum (C 0 )2 8 first radiation constant (C 1 )2 9 s.
E-26 u T o replace the battery 1 Remove the five screws that hold the back cover in place and then remove the back cover . 2 Remove the old battery . 3 Wipe off the sides of new battery with a dry , soft cloth. Load it into the unit with the positive k side facing up (so you can see it).
E-27 5 Replace the battery cover and secure it in place with the screw . 6 Press 5 to turn power on. Auto Power Off Calculator power automatically turns of f if you do not perform any operation for about six minutes. When this happens, press 5 to turn power back on.
