Answer 1

Hi

Answer 2

Hi @UnkleRhaukus

Answer 3

to insert in the figue into the document place "crt.png" in the same folder.
then just add
```
\begin{figure} [h]\includegraphics[width=0.6\textwidth]{crt} \end{figure}
```
to your code

Answer 4

I'm kinda confused. Do you have to save the document in a specific folder? Sorry, it's my first time adding images to my document

Answer 5

the document will save somewhere, in this folder there will be a
.aux , .log , .pdf , .synctex.gz , and a .tex file.

Answer 6

all with the same name as the document , usually you'd open the .tex file.

is this the same when you use Texmaker?

Answer 7

I should probably use texmaker, but I won't be able to share my progress with you. or could I ?

what about the the image below? I tried using this to upload the image, and it didn't work

Answer 8

I think I just lost everything

Answer 9

what happened

Answer 10

A red "lost connection" warning appeared, and then I lost everything...

Answer 11

you didn't have a copy saved?

Answer 12

I hit the back button...and that took me to the original template. Well I have a rough draft somewhere without the updates, and I have my handwritten equations in front of me, so I should be fine

Answer 13

Oh Yay It's back!

Answer 14

are you getting the picture to work yet ?

Answer 15

no, I think I saved the document by hitting the save button under "history", but I'm not sure where it's saving to

Answer 16

I see...I think I saved it now

Answer 17

so your document is online and not on your hard drive?

Answer 18

if it was me, i would have the file on my hard drive,

Answer 19

It's on my hard drive now, I think . It's saved on my desktop in a folder I labeled " LaTeX"

Answer 20

i placed the CRT.png in that same folder.

Answer 21

now just add
```
\begin{figure} [h]\includegraphics[width=0.6\textwidth]{crt} \end{figure}
```

it should work

Answer 22

It worked!

Answer 23

!YES!

Answer 24

Thanks soo much! You're awesome!!!

Is it possible to have the equations in two different columns?

Answer 25

yesh

Answer 26

\usepackage{column} ?

Answer 27

that might work , or you could just use align*

```
$$\begin{align*}
1111&&a\\
2&&b\\
3&&ccccc\\
4&&d
\end{align*}$$
```

$$\begin{align*}
1111&&a\\
2&&b\\
3&&ccccc\\
4&&d
\end{align*}$$

Answer 28

Thanks! I'll try that. Oh and one more thing, how can I make a table? or should I simply import a png image of my table in xcel?

Answer 29

```
$$\begin{array}{|c|c|}
\hline 1111&f&a\\
\hline2&q&b\\
3&w&ccccc\\
4&pppppppp&d\\
\hline
\end{array}$$
```

$$\begin{array}{|c|c|}
\hline 1111&f&a\\
\hline2&q&b\\
3&w&ccccc\\
4&pppppppp&d\\
\hline
\end{array}$$

Answer 30

Thanks again, you are awesome!!!! I'll save my work every couple of mins or so...just in case ;)

Answer 31

@UnkleRhaukus
I'm trying to have the equation line 37 to 41 on one side (where the 11111 2 3 4 are in your example) and the equations line 46 to 42 on the other side
Is that possible?

Answer 32

kinda like this

Answer 33

```
\[\\
\begin{array}{ccccccc}
&\text{Region 1}&&&&\text{Region 2}\\
\\
x_1=v_{ox}t_1& \text{or}& t_1=\tfrac{L}{v_ox}&(1)&&x_2=v_{ot}t_2\quad\text{or}\quad{t_2}=\tfrac D{v_{ox}}&(2)\\
\\
&y_1=\tfrac12a{t_1}^2&&(3)&&y_2+v_yt_2&(4)\\
\\
&v_y=at_1
\end{array}\]
```
\[\\
\begin{array}{ccccccc}
&\text{Region 1}&&&&\text{Region 2}\\
\\
x_1=v_{ox}t_1& \text{or}& t_1=\tfrac{L}{v_ox}&(1)&&x_2=v_{ot}t_2\quad\text{or}\quad{t_2}=\tfrac D{v_{ox}}&(2)\\
\\
&y_1=\tfrac12a{t_1}^2&&(3)&&y_2+v_yt_2&(4)\\
\\
&v_y=at_1
\end{array}\]

Answer 34

* the x should be in the subscript in (1)

Answer 35

is that working?

Answer 36

yep

Answer 37

goood

Answer 38

can you tell me what V_acc is in the diagram?

Answer 39

yep, it's the acceleration voltage. The electrons travel to the acceleration plates and acquire a velocity due to the voltage difference of 500V between those plates.

Answer 40

what do you think of this , i just made?

Answer 41

It looks identical to the CRT in my lab manual

Answer 42

did you really make this?

Answer 43

well i still have to put in the table in the left,

Answer 45

wow!!! that's madness!!!

Answer 46

any thing to fix?

do you want those extra vertical lines that i left out?

Answer 47

madness indeed

Answer 48

how did you make the coils? where the AC 6.3 Volts is?

Answer 49

its a circuit component , an inductor
its the

bit

Answer 50

Wow that's amazing! you mean this is for me? can I credit you on my paper. Copy right

Answer 51

Sure!

Answer 52

I'm totally awake now. Wow that woke me up!

Answer 53

( :

Answer 54

where did you learn to do that?

Answer 55

i learnt some Tikz a few months ago

i learnt some circuitkz a few weeks ago, mainly from the manuels and with help from tex.stackexchange.

Answer 56

I see...that's soo neat!!!

Answer 57

oh, i think i understand the accelerated voltage bit, the verticals lines are plates connected to wires that attach to a second power source

Answer 60

never mind, I figured it out =)

Answer 61

I have the table under the \section{Data} but when I after I compile the doc it appears before \procedure









\section{Data}

\begin{table}
\centering
\begin{tabular}{l|r|r}
Vy (Volts) & Deflection (mm) & Predicted Deflection (mm)\\\hline
0 & 0 & 0\\
2 & 1 & 1.12\\
4 & 2 & 2.24\\

Answer 62

*I have the table under the \section{Data} but after I compile the doc it appears before \procedure

Answer 63

* I meant \section{procedure}

Answer 64

did that work

Answer 65

\begin{tabular}[h]...

[h] for here

Answer 66

sorry I fell asleep again hahah..but yeah that worked!

Answer 67

your report is looking really good

Answer 68

I owe you!!!!!

Answer 69

what did I do wrong?

Answer 70

in excel right click on the chart and save as picture

Answer 71

I thought I did, I'm such a noob, I'm still learning though....don't give up on me just yet....

Answer 72

that abstract is still abstract

Answer 73

im still learning too

Answer 74

haha. Now that we're done with the graphics, I'm going to write/edit what's left. Man, I owe you. I learned a lot though. My next lab report should be a lot easier to create in LaTeX, now that have this template.
