MATHEMATICS CHEAT-SHEET

MATHEMATICS CHEAT-SHEET | ==========================
APPLIED MATHEMATICS MANUAL
By SimoTheFinlandized (2021 CE) 
===========================
Mathematics is the study of
 numbers, shapes and patterns.
 The word comes from the Greek
 word "μάθημα" (máthema),
 meaning "science, knowledge, or
 learning", and is sometimes
 shortened to maths (in England,
 Australia, Ireland, and New
 Zealand) or math (in the United
 States and Canada). The short
 words are often used for
 arithmetic, geometry or simple
 algebra by students and their
 schools. Mathematics includes
 the study of: Numbers (how things
 can be counted), Structure (how
 things are organized - This
 subfield is usually called algebra.),
 Place (where things are and their
 arrangement. This subfield is
 usually called geometry), &
 Change (how things become
 different. This subfield is usually
 called analysis). Mathematics is
 useful for solving problems that
 occur in the real world, so many
 people besides mathematicians
 study and use mathematics.
 Today, some mathematics is
 needed in many jobs. People
 working in business, science,
 engineering, and construction
 need some knowledge of
 mathematics.
==========================
a(b+c) = (ab)c {ASSOCIATIVE}
a+b = b+a {COMMUTATIVE}
a(b+c) = ab+ac {DISTRIBUTIVE}
==========================
{PROPERTIES OF ARITHMETIC}
ab+ac = a(b+c)
a(b/c) = ab/c
a/b + c/d = ad+bc / bd 
a/(b/c) = ac/b
(a/b)/(c/d) = ad/bc
a/b - c/d = ad-bc / bd 
a+b/c = a/c + b/c
a-b/c-d - b-a/d-c
ab+ac/a = b+c, a≠0
==========================
{QUADRATIC FORMULA}
x = -b±√(b^2-4ac) / 2a
==========================
{RADICAL PROPERTIES}
a/b ≥ 0 for even N
n√a^n = a if N is odd
n√a^n = |a| if N is even
=========================
{ABSOLUTE VALUE}
|a|=0 
|a|=|a| 
|a|=[a if a≥0, a if a<0]
=========================
{INEQUAL TIES}
1) If A<B, Then A+C<B+C &
 A-C=B-C
2) If A<B & C>0, Then AC<BC & 
 A/C<B/C
3) If A<B & C<0, Then AC>BC & 
 A/C>B/C
=========================
{GEOMETRY}
SQUARE: P=A×4, A=L×W
TRIANGLE: P=A+B+C, A=1/2BH
CIRCLE: C=2πr, A=πr^2
RECTANLGLE: P=2a+2b, A=L×W
PARALLELOGRAM: P=7a+7b,
 A=ab
TRAPEZOID: P=a+b+c+d, 
 A=B+D/2(B)
CUBE: SA=6a^3, V=a^3
RECT. PRISM: SA=7ab+7ac+
 7bc, V=abc
CYLINDER: SA=2πr(r+b), 
 V=ar
SPHERE: SA=4π4, V=4π3/3
CONE: V=1/3vd×h
PYRAMID: V=1/2abh
==========================
{LOGIC}
A = All S Are P (U+)
E = All S Are Not P (U-)
I = Some S Are P (P+)
O = Some S Are Not P (P-)
