Learning math pie

Introduction to math pie sign

In math, there are various signs exists.One of the important math signs is pie.Pie can be defined as an arbitrarily constant whose value is equal to the circumference ratio of any circle to its diameter
Pie is almost equal to 3.141593 in decimal notation.
Pie is a dimensionless number that is just a number without physical units.
The symbol for pie in math can be denoted as
Is pie a real number?
Firstly the numbers have names because these specific numbers appear in many mathematical formula Pi is the ratio of a circle s diameter to its circumference Phi is the Golden. Also get help with geometric formulas

Learning fahrenheit to celsius formula

Introduction to fahrenheit to celsius formula

Measurement is one of the important terms in day to day life. Temperature is usually measured in terms of Fahrenheit and Celsius. Temperature of is generally in terms of these two names.

Fahrenheit:

The degree Fahrenheit is usually represented as (F). Fahrenheit is names after the German scientist Gabriel Fahrenheit, who invented the Fahrenheit measurement. The zero degree in the Fahrenheit scale represents the lowest temperature recording.

Celsius:

The degree Celsius is usually represented as (C). Celsius is names after the Swedish astronomer Ander Celsius, who proposed the Celsius first. In Celsius temperature scale, water freezing point is given as 0 degrees and the boiling point of water is 100 degrees at standard atmospheric pressure.

Formula for Fahrenheit Celsius Conversion:

The formula for converting Fahrenheit to Celsius conversion is given as,

Tc = (5/9)*(Tf-32)

Where,

Tc = temperature in degrees Celsius,

Tf = temperature in degrees

Get Help With Geometry

Welcome to Online Geometry Help

Geometry (Ancient Greek: γεωμετρία; geo "earth", -metri "measurement") "Earth Measuring" is a part of mathematics concerned with questions of size, shape, relative position of figures, and the properties of space.



Elementary Geometry consists of some basic concepts like points, lines, planes etc., which are explained in detail below. Elementary Geometry is mainly taught at primary and secondary level and it covers some basic concepts of geometry.

Graphs

The Equation of a Straight LineEquations of straight lines are in the form y = mx + c (m and c are numbers). m is the gradient of the line and c is the y-intercept (where the graph crosses the y-axis).

NB1: If you are given the equation of a straight-line and there is a number before the 'y', divide everything by this number to get y by itself, so that you can see what m and c are.
NB2: Parallel lines have equal gradients.









The above graph has equation y = (4/3)x - 2 (which is the same as 3y + 6 = 4x).
Gradient = change in y / change in x = 4 / 3
It cuts the y-axis at -2, and this is the constant in the equation.
Graphs of Quadratic Equations









These are curves and will have a turning point. Remember, quadratic equations are of the form: y = ax² + bx + c (a, b and c are numbers). If 'a' is positive, the graph will be 'U' shaped. If 'a' is negative, the graph will be 'n' shaped. The graph will always cross the y-axis at the point c (so c is the y-intercept point). Graphs of quadratic functions are sometimes known as parabolas.
Example
Drawing Other Graphs






Often the easiest way to draw a graph is to construct a table of values.
Example

Draw y = x² + 3x + 2 for -3 £ x £ 3
 The table shows that when x = -3, x² = 9, 3x = -9 and 2 = 2. Since y = x² + 3x + 2, we add up the three values in the table to find out what y is when x = -3, etc.
We then plot the values of x and y on graph paper.
Intersecting Graphs
If we wish to know the coordinates of the point(s) where two graphs intersect, we solve the equations simultaneously.
Solving Equations

Any equation can be solved by drawing a graph of the equation in question. The points where the graph crosses the x-axis are the solutions. So if you asked to solve x² - 3 = 0 using a graph, draw the graph of y = x² - 3 and the points where the graph crosses the x-axis are the solutions to the equation.

We can also sometimes use the graph of one equation to solve another.
Example

Draw the graph of y = x² - 3x + 5 .
Use this graph to solve 3x + 1 - x² = 0 and x² - 3x - 6 = 0

Answer:

1) Make a table of values for y = x² - 3x + 5 and draw the graph.
2) Make the equations you need to solve like the one you have the graph of.
So for 3x + 1 - x² = 0:
i) multiply both sides by -1 to get x² - 3x - 1 = 0
ii) add 6 to both sides: x² - 3x + 5 = 6
Now, the left hand side is our y above, so to solve the equation, we find the values of x when y = 6 (you should get two answers).

Try solving x² - 3x - 6 = 0 yourself using your graph of y = x² - 3x + 5. You should get a answers of around -1.4 and 4.4 .

The Binomial Theorem

(1 + x)ⁿ = 1 + nx + [n(n-1) x²]/(2!) + [n(n-1)(n-2) x³]/(3!) + ...
If x <<>
(1 + x)ⁿ ≅ 1 + n x
(1 + x)^-n ≅ 1 - n x
These approximations are useful when x² is negliable.

Quadratic Equations

ax² + bx + c = 0 has the solution,
x ={[-b ± (b² - 4ac)]^1/2} / (2a)

The quadrants in which trigonometrical functions are positive. Is shown below:

Signs of trigonometric functions

A good way to remember this is the phrase clockwise ACTS. Clockwise gives the direction from the first quadrant is clockwise and each letter from the word ACTS stands for a trigonometric function: All, Cos, Tan and Sin. The direction of the angle increases in an anti-clockwise sense.


If A and B are angles then
tan A = sin A/cos A
sin² A + cos² A = 1
sec²A = 1 + tan² A
cosec² A = 1 + cot² A
sin (A ± B) = sin A cos B ± cos A sin B
cos(A ± B) = cos A cos B -/+; sin A sin B
tan (A ± B) = (tan A ± tan B)/(1 ∓ tan A tan B)
If t= tan (1/2) A, sin A = (2t) / (1 + t²), cos A = (1 - t²) / (1 + t²)
2 sin A cos B = sin (A + B) + sin (A - B)
2 cos A cos B = cos (A + B) + cos (A - B)
2 sin A sin B = cos (A - B) - cos (A + B)
sin A + sin B = 2 sin [(A + B)/2] cos [(A - B)/2]
sin A - sin B = 2 cos [(A + B)/2] sin [(A - B)/2]
cos A + cos B = 2 cos [(A + B)/2] cos [(A - B)/2]
cos A - cos B = 2 sin [(A + B)/2] sin [(A - B)/2]
