Drawing is a form of visual art in which an artist uses instruments to mark paper or other two-dimensional surface. Drawing instruments include graphite pencils, pen and ink, various kinds of paints, inked brushes, colored pencils, crayons, charcoal, chalk, pastels, erasers, markers, styluses, and metals (such as silverpoint). Digital drawing is the act of using a computer to draw. Common methods of digital drawing include a stylus or finger on a touchscreen device, stylus- or finger-to-touchpad, or in some cases, a mouse. There are many digital art programs and devices.
A drawing instrument releases a small amount of material onto a surface, leaving a visible mark. The most common support for drawing is paper, although other materials, such as cardboard, wood, plastic, leather, canvas, and board, have been used. Temporary drawings may be made on a blackboard or whiteboard. Drawing has been a popular and fundamental means of public expression throughout human history. It is one of the simplest and most efficient means of communicating ideas. The wide availability of drawing instruments makes drawing one of the most common artistic activities.
In addition to its more artistic forms, drawing is frequently used in commercial illustration, animation, architecture, engineering, and technical drawing. A quick, freehand drawing, usually not intended as a finished work, is sometimes called a sketch. An artist who practices or works in technical drawing may be called a drafter, draftsman, or draughtsman.
Some time ago, I drew a simple drawing. But now I can't remember how I drew it. Did I use a software or a website?
I remember I could choose some optics components, like the small laser in the image, the mirror mount, etc.
It can do basic light tracing.
It was free.
Attaching the image of the problem as an image. Somehow text is not copied from the book.
Somehow, I can't imagine the picture in my head. We can do it in 2D plane. I know, it mentions the solution, but need to see the drawing, otherwise, my logic fails.
I thought that maybe, first half space...

I tried drawing the structure, and I do not know which one of the two is the correct compound for the nomenclature.
Which one would be the correct one, and why?
Thank you!
I have just attached a standard depiction of a radial field as one may similarly choose to draw it. So I understand that the gravitational field strength in a field is defined as the force per unit mass at that point. The field lines in a radial field move further apart further away from the...
The picture above is the correct answer, but I do not understand why.
I thought that the OH group on the top has to be prioritized and be numbered 1.
But then, the structure would have to be named 2,4,6-trimethylphenol, not 1,3,5-trimethylphenol.
For example, 4-chloroaniline structure looks...

Just wanted to give a shoutout to SchemDraw, a FOSS circuit schematic drawing package for Jupyter(Python), made by a PhD at Sandia Labs. It's purely drawing, not simulation of any kind, but given Python's numeric and symbolic superpowers it's easy enough to bolt-on that functionality.

The interval sketch is obviously a line from 0, 1.
F1 would cut the interval line by a third similar to the Cantor set.
F2 would cut the interval line by a third and then there is a transformation that moves to the point (1/3, 1/3).
F3 would cut the interval line by a third and then...
I ultimately want to make a sewing pattern of a ball. If I have an n-hosohedra, how do I figure out the equation of the curves that make up each lune in 2D?

This is correct according to my book. The follow up question then becomes, what if you can pick 5 of any suit, 3 of any other suit, another 3 from the remaining 2 suits and 2 from the last untouched suit?
The solution...

I tried saying z = x + iy, then squared both sides so that I would get something that looked like:
|z - i|^2 + |z + i|^2 + |z - i||z + i| = 3, where the first two terms are simple but the third term is what I don't know what to do with. I'm wondering if I'm using the wrong approach.
For that...
Hello, good morning.
I would like to know if someone knows a program to be able to draw the functions in the same way as the one shown in the image and also allow me to point out an enclosure formed by them without having to use inequalities to do so.
Thank you very much for everything beforehand.

Hi, how would I go about drawing these two graphs?
and
The first one would be concentric circles with the centre at (0,0).
The second one would be straight lines through (0,0).
Is this correct?
Also, what happens at ln(0) = constant for the first graph and x = 0 for the second graph...
The only one that I can see is for the potential $$V=-\frac{2GM}{3r}$$ since the midpoint of the two masses satisfies this equation. The only other useful inference I can make is that the most negative potentials closes to the surface of either planet, and the lowest potentials will be far away...
QS) A model of a bus has a scale of 4cm to 3m. The model is 10cm long. What is the real length of the bus?
my workout: 4cm to 3m. 4 cm is length of model and 3m is real length.
so we have, mode = 10 cm long
so 4 cm to 10 cm: 10/4= 2.5 cm
for real length 3 X 2.5= 7.5 m.
