 I was looking through the forum's official LaTeX post and found out that Melody has already found out the \mathbf command which can be used with the above commands while I am still using that stupid \textbf command. LOL.

But \textbf is also useful too. If you want to type text and not to use something like \; , \space.

TextBF:  LaTeX code: \textbf {Max is so clever}

MathBF:  LaTeX code: \mathbf {Max\space is\space so\space clever}

You can see that TextBF need not be done spacing with \space while MathBF must have be done spacing with it.(Sorry for bad grammar I am from China)

 

Pros and Cons of TextBF

Pros: Spacing is easier.

Cons: Couldn't be used with math mode formulas

 

Pros and Cons of MathBF

Pros: Math mode formulas can be used in mathbf

Cons: Spacing takes more time

Q:Why to type \log in LaTeX?

A:If you just type log in LaTeX, it will automatically think that l, o, and g are variables, and it will automatically become italic. If you typed \log, it will be normal but not italic.

LaTeX code 'log' : 

LaTeX code '\log' : 

Also I found out \sin , \cos, and \tan works too

LaTeX code 'sin':    

LaTeX code '\sin':

LaTeX code 'cos':     

LaTeX code '\cos':

LaTeX code 'tan':

LaTeX code '\tan':

I am going to share 2 LaTeX commands which make you spend less time spacing.

I found it this myself. \text{}

It does  Latex command: \text{I am Max}

 

I think this does the same thing and I first saw it from a reply from Melody. \mbox{}

It does  Latex command: \mbox{I am Max}

Also I have found a way to use LaTeX without even clicking the LaTeX button.

Type '\(' 

and then type '\)'

and then type your LaTeX commands between the 2 notations.

Example:

In this example I just typed \(

and then \text{Hi}

then \).

I didn't even click LaTeX button :)

Inequalities:Example 1:      Latex code: x+1 \geqslant 0

                   Example 2:      Latex code: x-1 \leqslant 0

 

Instead of \geqslant and \leqslant you can use

 

Latex code: x+1\geq0

Latex code: x-1\leq0
