## What is Grapher on a Mac?

Grapher is **a computer program bundled with macOS since version 10.4 that is able to create 2D and 3D graphs from simple and complex equations**. It includes a variety of samples ranging from differential equations to 3D-rendered Toroids and Lorenz attractors.

**How do you make an imaginary on Desmos?**

To get the real or imaginary part of a number/point a, **do a.x or a.y respectively**. Desmos can add and subtract points just like complex numbers. To define your own complex number, type a = (real,imaginary). The points will appear in the graph like it is in the complex plane.

**How do you label imaginary axis?**

for example: z = 4 + 5i, where x and y are real numbers, and **i is the imaginary unit**. In this customary notation the complex number z corresponds to the point (x, y) in the Cartesian plane.

**How do you plot a grapher?**

**Adding a New Plot:**

- Click anywhere on the graph to select it.
- Click the Home| Add to Graph | Plot command ( ).
- In the Select Plot Type dialog, click your desired plot type and then click OK. ...
- In the Choose Axes dialog, be sure to select X Axis 1 and Y Axis 1 and click OK.
- Select the data file and click Open.

**What does the imaginary unit i equal?**

What Are Imaginary Numbers? The imaginary number i is equal to **the square root of -1**. In other words, i^{2} equals -1. The square root of a negative number is not a real number and it is not a variable.

**How do you represent complex numbers?**

The standard form of writing a complex number is **z = a + ib**. The standard form of the complex number has two parts, the real part, and the imaginary part. In the complex number z = a + ib, a is the real part and ib is the imaginary part.

**Is 3i a complex number?**

**−3i is an imaginary number, it is the imaginary part (bi) of the complex number a + bi**. This imaginary number has no real parts, so the value of a is 0.

...

Imaginary Numbers | |
---|---|

3i (b = 3) | −672i (b = −672) |

(b = ) | (b = ) |

**What is a conjugate of an imaginary number?**

You find the complex conjugate simply by **changing the sign of the imaginary part of the complex number**. Example. To find the complex conjugate of 4+7i we change the sign of the imaginary part. Thus the complex conjugate of 4+7i is 4 - 7i.

**How do you make a subscript on Desmos?**

When you need a subscript just **push the alt button in the keypad.** **Then click on the button with the a^b power**. It will switch the button to a (subscript) b. When you are finished just "left click" the mouse right next to it and begin typing the rest of the equation.

**Why complex numbers are denoted by Z?**

Generally a complex number is of form x+iy so real part of it is x and imaginary part is y. So, maybe z (**as x and y are already used and z comes after y**) is used to represent the complex number.

**Is the y-axis imaginary?**

**The vertical number line (the y-axis on a Cartesian plane) is the imaginary axis**.

**What do imaginary zeros look like on a graph?**

This negative square root creates an imaginary number. The graph of this quadratic function shows that there are no real roots (zeros) because the graph does not cross the x-axis. Such a graph tells us that the roots of the equation are complex numbers, and will appear in the form **a + bi**.
