Mathematics For Chemist

Mathematics for chemist or general mathematics needed in chemistry include chapter of basic mathematics of upto class 10 and some chapters of higher classes like Vectors, Matrices and Linear Algebra, Differential Equations, Differenciation, Intigration, Group Theory.

Maths For Chemist

Vector

Vector is a quantity having magnitude and direction. example- Force, Weight etc.

Matrices

Its singular form is Matrix, It is a rectangular array of numbers or symbols and these numbers and symbols are arranged in rows and columns and one can perform operation on it as per defined rules to solve matrices.

Linear Algebra

Linear Algebra is a mathematical tool to define any thing in 2D ( Two Dimensional) but may be extended to 3D, 4D,5D..... so on as per requirement.

Differential Equations

Differential Equations is an mathematical equation which involvs derivatives of a function or functions.

Differenciation

Differenciation is process or action of differentiating.

Intigration

Intigration is process or action of intigrating.

Group Theory

Group Theory is a tool to analyse any thing or system which have symmetry and posseses symmetry element.

Maths 5th Class

5^th Class Mathematics

Mathematics is very necessary in understanding chemistry very well, so we now publish some basics of mathematics from class 5th maths. Hope you like our work.

Multiplication:  operation to get no. of times of given no. eg- 5x5 = 25

Vedic trick of multiplication-

HCM (Highest Common Multiple) and LCM (Lowest Common Multiple) :

HCM: 5

LCM: 5x3x2x5x7=1050

Fraction=Numerator/Denominator

Profit = selling price - cost price

Loss = cost price - selling price

Profit% = (profit x 100)/cost price

Loss% = (loss x 100)/cost price

Amount = principle + interest

Simple Interest = principle x rate% x time

Simple Interest = (principle x rate x time)/100

AM = antemeridian

PM = postmeridian

Big Units	Small Units
Kilo = 1000 times	Deci = 1/10
Hecto = 100 times	Centi  = 1/100
Deco = 10 times	Mili = 1/1000

Perimeter:

Perimeter of Triangle = sum of lengths of all three sides of triangle.

Perimeter of Rectangle = 2 (Length + Breadth)

Perimeter of Square = 4 x ( Length of any one side)

Area:

Area of Rectangle = Length x Breadth

Area of Square = Side x Side

Different Angles used in Mathematics:

• Acute Angle < 90^o

• Right Angle = 90^o

• 90^o < Obtuse Angle < 180^o

• Zero Angle = 0^o

• Straight Angle = 180^o

Different Triangles used in Mathematics:

• Right Triangle = Triangle containing one 90^o angle

• Equilateral Triangle = Triangle having three equal sides and three equal angles, and have each angle of 60°.

• Isosceles Triangle = Triangle having two equal sides and two equal angles.

• Scalene Triangle = triangle having different length of sides.

• Acute Triangle = Triangle having all three angles less than 90^o

• Obtuse Triangle = Triangle having one angle more than 90^o

 

Vector : What is vector? in Physical and Mathematical Term

What is vector?
Vector is a quantity which poses magnitude as well as direction.

Examples of vector
Force, velocity etc.

What is free vector?
A vector which is permitted to move in anywhere in space according to their length and direction, is known as free vector.

What is bound vector or sliding vector?
It is a vector constrained to act along the given line is known as bound vector or sliding vector.
