Getting Started Welcome to your HP 35s Scientific Calculator This guide is a supplement to the HP 35s Scientific Calculator User’s Guide, and it is intended to provide the user with basic operational information about the calculator. For more detailed information about the many capabilities of the HP 35s Scientific Calculator outlined in this guide, refer to the complete user’s...
CR2032 (or equiva- lent) batteries as soon as possible. See appendix A of the HP 35s Scientific Calculator User’s Guide for instructions. Adjusting Display Contrast The display contrast depends on lighting, viewing angle, and the contrast setting.
Keyboard Features of the Keyboard Shifted Keys Figure 1 Calculator Keyboard • Cursor keys have only a yellow shift function. • Most keys have three functions: one printed in white, a yellow- shifted-function printed above the key, and a blue-shifted function printed on the angled face of the key (See Figure 2).
Figure 2 Key Diagram Left-shifted function Letter for alphabetic Right-shifted function Alpha Keys Keys with a pink letter displayed on the bottom right corner are alpha keys, used commonly to enter variables or program labels. When you are prompted for a letter entry, the A..Z sym- bol appears in the display, and the alpha keys are active.
Table 1 Backspace and Clear Operations Description Backspace and Clear. If an expression is in the process of being entered, pressing erases the character to the left of the entry cursor ( _ ). Otherwise, with a completed expression or the result of a calculation in line 2, replaces that result with a zero.
Undo also recovers the values of a register, or registers, just cleared using the CLEAR menu, if the undo operation immedi- ately follows the cleared operation. Using Menus Sixteen of the keys are menu keys, keys which permit access to more functions.

pages available. Use the Õ and Ö cursor keys to move to an item on the current menu page; use the × and Ø keys to access the next and previous pages in the menu. Exiting Menus Whenever you execute a menu function, the menu automatically disappears.
Operating Modes The HP 35s has two operating modes: Reverse Polish Notation (RPN) and Algebraic mode (ALG). RPN is usually more efficient than Algebraic, requiring fewer key presses to solve most prob- lems. It is also particularly helpful when working through a prob- lem one step at a time, as all intermediate answers are displayed.

number that was in the X–register before the last numeric func- tion was executed. Pressing ºÍ returns this value into the X–register. Retrieving the "last x" has two primary uses, correct- ing errors and reusing a number in a calculation. For example, suppose you wanted to find the square root of a number, but pressed by mistake.

9 rather than 7. Memory and Variables The HP 35s has 30KB of memory for storing numbers, equa- tions and programs. Numbers are stored in locations called variables or registers. Variables are named with a letter from A to Z, giving 26 directly addressable memory registers.
tions. These variables are always available for use. For exam- ple, in ALG mode, to save the currently displayed value into register Q, press ºeQÏ. To recall the value to use it again, press hQÏ. The stack registers X, Y, Z, and T are not the same as the memory registers with the same letter.

or example, since the speed of light, c, in meters per second is the first constant on the first page of the constants menu, to sub- tract one meter per second from it in ALG mode, press ¹ÜÏÃ1Ï Figure 7 Note: constants are referred to by their symbols rather than their numeric values when used in expressions, equations, and pro- grams.
Figure 8 To display values entered as fractions use the Fraction Display ºÉ. Figure 9 If values are displayed as decimal values, pressing ºÉ changes the display view to show fractions. Pressing it again changes the display back to decimal values. More exact control of the fraction display is possible using the ¹Ê...

4 complex numbers at one time. In ALG mode, an expression can contain as many complex numbers as needed. The HP 35s processes complex arithmetic (+, –, x, ÷), complex trigonometry (sin, cos, tan), and the mathematics functions –z, 1/z, ln z, and .
5+6i, in either RPN or ALG mode, press 566 to enter the vector, then press to place the HP 35s into the complex number rθa display mode. The magnitude is displayed as the 7.81 portion of the complex number as shown in the display graphic above.

well as the sample and population standard deviations. Statisti- cal data are entered using the / key. If you make a mistake entering a value or values, key them in again and press ¹- to remove them. For example, suppose you wish to find the average X and Y val- ues of the following set of data points: (1,2), (4,5), and (9,4).
¹( in either mode. Linear Regression The HP 35s can estimate the equation of a straight line that best fits a set of (x,y) real number data points. For example, suppose you wish to fit a straight line to these data points: (1,2), (4,5), and (9,4).

pressing 1Ï2/4Ï5/9Ï4/. To view the results of the linear regression, press ¹% to view the linear regression menu.

The HP Solve and integration features can be extended to work with programs as well as expressions. Pressing the d key displays the HP 35s equation cata- log. Figure 19 If there are no user- entered equations, the display appears as shown at right.
You can specify that an equation evaluates, solves for unknown values (find roots), and is used for numeric integration. Evaluating Expressions The HP 35s evaluates expressions entered into the equation list. For example, if you wish to evaluate X –4 for various values of X, press d and then press hX)2Ã4Ï.
Page 34
The display shows the value of the expression when X=3, which is 5. Figure 22 To evaluate the expression at another value of X, press the d key, then Ï, and key the next value of X and ¥. This operation can be repeated as often as you may need to evalu- ate the expression at different values of a variable.
Ï1¥3¥. Figure 24 Finding Roots of Equations The HP 35s can find roots of equations entered into the equa- tion list. For example, suppose you wish to find the roots of the polynomial, X – 3X + 2 = 0. First, enter the equation into the equation catalog.
Integrating Expressions The HP 35s numerically integrates expressions in the equation catalog or program routines that define the function to be inte- grated. Note: the display mode is used to specify the desired...

by pressing the letter key X. The message “INTEGRATING” briefly displays before the result of 1.39 appears. Figure 30 For another example, to integrate Te from 0 to 10, first enter the expression into the equation catalog by pressing dhT¸º#zhTÏ. The display appears as shown below.

Not every system of linear equations has a solution. Some sys- tems have an infinite number of solutions. The linear solver equations built into the HP 35s detects situations where no solu- tion exists, or where an infinite number of solutions exist.
Page 40
Figure 33 Begin the solution by pressing ºÛ. The HP 35s prompts for the entry of the six coefficients, which are stored in lettered variables A through F. The value stored in variable A is dis- played, which you may use by pressing ¥, or replace by key- ing in another value and pressing ¥.
annunciators at the right of the display indicate that more information exists. Press Ø to display the value found for Y. Figure 36 The solution to this 2 by 2 system is {X = 4, Y = – 2}. Solving 3 by 3 linear systems is done in the same manner.
• Saving space by using portions of a program requiring multiple executions as subroutines. • Indicating an intermediate result by pausing to display the current contents of the X register. Suppose, for example, you need to compute the areas of sev- eral circles.

Now, enter the program by typing: ¹Ô. Each line of the program ºÓA ¹ begins with the letter of the label and then has a three–digit line number. (See displays below). Figure 38 Figure 39 Figure 40 The rest of the program line is a function or program instruction. The program instructions here are the Ó...
To use this program, press ¹Ô to move out of program mode and return to the top of the program. To calculate the area of a circle with a radius of 5, make sure RPN mode is set (9 ) and press ¥.
Page 45
Here is a step-by-step explanation of this program: Program line B002 is an instruction to set ALG mode, to make sure program B is not accidentally used in RPN mode. If you always work in ALG mode, or if you always remember to switch to the proper mode before using this program, then this pro- gram line is not needed –...
