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.

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, i2 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?

Remember that a complex number has the form a + bi. You need to figure out what a and b need to be. Since −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.

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.
