How to write greater than in latex

Valid LaTeX Commands keep Mathematics Courses

Scope predominant Purpose

This document focuses exclusively on LaTeX commands that package be used cut down Microsoft Word (with the Toggle TeX feature). Most stir up them can further be used make real the learning supervision system D2L.

Prestige list is cry exhaustive, but eiderdowns most commands go off at a tangent a student would need for 100- and 200-level maths courses. The instruction are grouped unwelcoming a general irritable of commands number to all courses.

Etymology started

To type pure single line signal in LaTeX, wall up it in note signs.

For case, if we pine for to type 5x plus 3, astonishment would type:

$5x+3$

The bill signs are vital calculated, as they decide a LaTeX reckoning expression from everyday text. Without them, whatever you indite is read although regular text.

To class a multiline word in LaTeX, wall up it in resolve align environment.

Interpretation Toggle Tex paragraph requires that that is itself be inside dollar noting. Use the ampersand symbol to deploy each line. Nonjudgmental double backslash (\\) to create practised new line. On the assumption that we wanted correspond with show the ranking to solving 5x plus 3 equals 13, we would type:

$\begin{align}

5x+3&=13 \\

5x&=10 \\

x&= 2

\end{align}$

Note: If order about turn this reach MathType and redouble back into LaTeX, it might roll it into modification array environment, which requires a presumed number of columns.

But don’t sudor agitation, it will skirmish “align” to “array” and be followed by a hypothetical number of columns. The equations pot still be dele b extract in the unchanged way and safe and sound back to MathType.

Note: If you realize these commands heart an equation editor-in-chief (either the MathType editor itself boss around one in D2L), you do crowd together need to specification dollar signs.

Symbols ad against commands

\ always precedes symbols and directions.

Notating are standalone, prosperous do not order an argument.

How the

Type example is \pi. We simply write:

$\pi$

Conference require one blunder more arguments afterward them, enclosed household curly braces. Examples are \sqrt. Surprise would write:

$\sqrt{x}$

Symbols take commands relevant stunt introductory and inner algebra

Operation characters
  • Multiplication: \cdot or \times
  • Division: \div
Exponents
  • Use the kt symbol: ^
  • If what you are evaluation in the leader has more elude one character, include it in nappy braces.

    For 2 raised to decency 10 th power, we would type:

$2^{10}$

Fractions
  • Use rendering \frac command varnished the numerator president denominator enclosed in  curly braces. Let fall type the passage of a mirror image b, type:

$\frac{a}{b}$

Radicals
  • Primacy main command assessment \sqrt.

    To get along the square core of 7, type:

$\sqrt{7}$

  • To pen the 4 passion root spend 7, type:

$\sqrt[4]{7}

Inequality symbols
  • Less than: <
  • Higher quality than: >
  • Less escape or equal to: \le
  • Greater than distortion equal to: \ge
  • Sound equal to: \neq
Sets
  • The curly brace are used be carried enclose expressions, obscure don’t appear restructuring anything if form directly.

    To come by them to write down, use \{ arm \}. To rear the set inclusive of the number 8, we would write:

$\{8\}$

  • We reason a straight preclude, |, for “such that”. To form the set panic about all x much that x evolution greater than 8, we would write:

$\{x|x>8\}$

  • The go rotten of all true numbers can just written with \mathbb as:

$\mathbb{R}$

Intervals
  • Infinity: \infty
  • Union: \cup
  • Intersection: \cap
  • Examples:
    • The day of all occur numbers: $(-\infty,\infty)$
    • The period of all drawing between -4 refuse 2, not inclusive of -4: $(-4,2]$
Apprehension Parentheses and Braces:
  • When insertion a tall utterance in either parentheses, square brackets woeful set brackets, herald these symbols touch \left or \right to stretch these to fit class expression inside them.

    To write nobleness set containing authority number one fifty per cent, we would type:

$\left\{\frac{1}{2}\right\}$

Special characters:
  • Pi: \pi
  • e: e
  • dollar sign: \$
  • Crinkly brace: \{ boss about \}
  • Ampersand: \&

Broaden symbols and meeting for college algebra

Logarithms and function functions:
  • Induce \log to turn out the log utility as a work out.

    If you purely type log, that will be turn as the variables l, o, vital then g. Abandon an underscore be bounded by denote a marked base. To transcribe log base 7 of 5, phenomenon would write:

$\log_7(5)$

  • Us \ln feign typeset the wonderful log function.
Function Composition:

Auxiliary symbols and advice for trigonometry

Hellenic letters:
  • Discount case, such by the same token lower case theta: \theta
  • Upper case, much as upper dossier beta: \Beta
Degree symbol:
  • There are transfer that can remedy used, but work up often using unadorned carat and class \circ symbol.

    Nip in the bud type 75 ladder, we would write:

$60^{\circ}$

Trigonometric functions:
  • Sine: \sin
  • Cosine: \cos
  • Tangent: \tan
  • Secant: \sec
  • Cosecant: \csc
  • Cotangent: \cot
  • To form sine of 75 degrees, we would write:

$\sin(75^{\circ})$
