Functions allow you to automate common tasks in a more powerful and general way than copy-and-pasting. Writing a function has three big advantages over using copy-and-paste: You can give a function an evocative name that makes your code easier to understand. As requirements change, you only need to update code in one place, instead of many.

Choose between using your calculator in Algebraic mode or RPN mode. Number Format Choose between standard notation, scientific notation, and engineering notation.

Note that the decimal point will not appear unless if you are dealing with approximate values. FM, In some places of the world, the decimal point is replaced by a comma.

If you use a decimal point in the place of a comma, check this box by pressing. Otherwise, leave it unchecked. Choose how you want to measure your angles — degrees, radians, or grads.

Coordinate System Choose between using rectangular 3D coordinates, polar cylindrical coordinates, or spherical coordinates.

Coordinate points and vectors on the stack will automatically be converted. Beep Every time there is an input error, the calculator will accompany the error message with a beep.

If you are using the calculator during a test or in a quiet place, turn it off. Key click Every time that you press a key, a high pitched noise will be given as feedback, which may come useful presumably if you are wearing gloves while using your calculator.

Last stack Keep this on; it lets you undo your work. We recommend switching the following flags: It is highly subjective, but since you can access the number pad and do not need to access the function layer white print actively while, it would typically save you time. Choose boxes typically disrupt your workflow and are relatively clunky to use, so toggle the flag on and use soft menus instead.

Note that certain features, especially the STAT menu, are only available as choose boxes. Learning RPN The first thing you should notice is that the home screen looks significantly different now.

The main or only difference is that instead of the calculator displaying your previous calculations, you are instead greeted with a stack.

The stack has many uses, depending on how you want to use it.

It is used as a history archive for past calculation results, previous versions of a program that you may be making, or a workspace for a calculation. A large stack, however, may quickly slow down your calculator, so it is recommended to keep the stack clean.

You can manipulate the stack either by calling functions, or by entering values.

Once you remove an element from the stack, all of the elements above it will drop down one, and once you insert an element into the stack, all the elements above it will pop up by one. Once you get used to it, the concept of stack manipulation will come naturally.

The numbers on the left are the stack levels. The first level is level 1, the second level is level 2, and so forth.

The addition function takes two values from the stack and returns the sum as one value.A beautiful, free online graphing calculator from leslutinsduphoenix.com Apache/ (Scientific Linux) Server at leslutinsduphoenix.com Port In this section we will discuss graphing lines.

We will introduce the concept of slope and discuss how to find it from two points on the line. In addition, we will introduce the standard form of the line as well as the point-slope form and slope-intercept form of the line.

We will finish off the section with a discussion on parallel and perpendicular lines. Algebra 1A Chapter 4: Graphing Linear Equations and Functions Date Homework Objective M Jan 3 p #1, odd, ,24,36 SwBat identify and plot points in a coordinate plane. the graph of the sine function.

The general form of the sinusoidal functions sine and cosine are y = a sin he is over land. Write a trigonometric function that models the distance 4: 3 5 P M 10/30/09 PM. Title: 00i_PCCRMC04_indd. We at Calcblog hope you had a great winter vacation!

So far, we’ve posted tutorials on graphing in rectangular/Cartesian and polar coordinates, but there are other ways to specify leslutinsduphoenix.com of these is as a function of a .
