Calculus Problem Help

Introduction to calculus problem help:-

In this lesson lets study about calculus problems online. Before i teach you on calculus issue let me help you what is calculus and how does it importance to arithmetic.

What is calculus?
Calculus (Latin, calculus, a tiny stone used for counting) is a branch in arithmetic focused on limits, functions, derivatives, integrals, and boundless series. This subject constitutes a major part of modern arithmetic schooling.

Example issue on calculus:

Query: Differentiate the given equation with respect to t. y = - 2t3 + 8t2 + 46t.

Solution:

Given: y = - 2t3 + 8t2 + 46t.
Differentiate with respect to t,
dy = - (2 × 3)t(3 - 1) dt + (8 × 2)t(2 - 1) dt + 46t(1 - 1) dt.

= - 6t2 dt + 16t dt + 46 dt.

= (- 6t2 + 16t + 46) dt.

dy / dt = - 6t2 + 16t + 46. This could also help us on calculus problem solver

Answer:

d/dt(- 2t3 + 8t2 + 46t) = - 6t2 + 16t + 46.

Arithmetic progression

Introduction to Arithmetic progression:

In this article, we shall discuss about arithmetic progression. Progressions are of two types .They are arithmetic and geometric progression. An Arithmetic progression which consists of the sequence of numbers and the terms except the first can be obtained by adding one number to its preceding number. Arithmetic progression is denoted as the arrangement of two consecutive numbers, the progression which is constant.

Example Problems for Arithmetic Progression

Example 1:

The sequence terms of an A.P. 6, 1, –4...Find the 10th term.

Solution:

Consider the A.P in the form a, a + d, a + 2d, ...

Here, a = 6, d = 1 – 6 = –5, n = 12

tn = a + (n–1) d. This could also help us on grade 9 math

t10 = 6 + (10 – 1) (–5) = 6 + 9 x (–5) = 6 – 45 = – 39
:.The 12th term is –39.

corresponding angles

Introduction to corresponding angles
In this section let me help you on corresponding angles, an angle (in full, plane angle) is the figure formed by two rays sharing a common endpoint, called the vertex of the angle.[ The magnitude of the angle is the "amount of rotation" that separates the two rays, and can be measured by considering the length of circular arc swept out when one ray is rotated about the vertex to coincide with the other (see "Measuring angles", below). Where there is no possibility of confusion, the term "angle" is used interchangeably for both the geometric configuration itself and for its angular magnitude. Now let us see about the corresponding angles

Corresponding Angle Sum
Corresponding angle Example:What are the measures of the other angles in the diagram? Suppose that angle1 has a measure of 60º

Answer:
Angle 8 is also 60º since it is vertical to angle 1. This could also help us on Prime factorization Calculator.
Angle 2 has a measure of the 60º since it is a corresponding angle 3to angle 1.

Angle 5 has a measure of 60º since it is vertical with angle 2, and also since it is an alternate exciter angles to angle 1.

Another angle is all corresponding angles 1, 2, 5, and 8 have a measure angles are 120º.

Introduction to obtuse triangles

Introduction to obtuse triangles:

There are three types of triangles ( based on size of angles ), namely

* Acute angled triangles ( triangles with angles measuring less than 90 degrees)
* Right angled triangles ( triangles with one angle measuring exactly 90 degrees) and
* Obtuse angled triangles ( triangles with one angle measuring more than 90 degrees)

Obtuse triangle is also called obtuse angled triangle. Unlike acute triangles, where there can be three acute angles in a triangle, an obtuse triangle can have only one obtuse angle.

Obtuse Angle

Before going deeper, we need to know what an obtuse angle is. Obtuse angle is an angle that measures more than 90 degrees. This could also help us on mole fractionThis is an obtuse angle. Here angle ‘a’ is the obtuse angle.

Help on Expression Calculator

Introduction:

Today let me help you understand on expression calculator. Expressions are defined as finite combination of numbers and symbols that are well performed according to rules. Expressions are considered to be the major part of algebra. Algebra consists of numbers and variables. Algebraic expressions consist of finite combination of numbers and variables.In this article, we are going to see about solving expressions calculator.

Solving Expressions Calculator:

Solving expressions calculator is used to find the value for the given expression. Solving expressions calculator are very helpful for the students who lacks in arithmetic operations. Using these calculators, hard problems can be solved easily. When the given expression is entered in the calculator, it automatically delivers the output.The diagrammatic representation of the solving expressions calculator is shown below. This could also help us on cubic yard calculator.

Solving Expressions Calculator: -

Example:

Simplify 25x – 17x, by combining like terms.

Solution:

Here the like terms are x,

= 25x – 17x

Taking common terms outside,

= x (25-17)

= 8x

The answer is 8x.

Introduction to Alphabet of lines

Introduction to Alphabet of lines

In this leasson let me help you on alphabet of lines. In order to understand what the line is trying get across, you must be able to understand the symbols. The standard thickness of the line is 0.030 to 0.038 inches. The standard thin line weight varies from 0.015 to 0.022 inches.

Main Types of Lines

There are 09 types in lines. They are,

1) Visible Lines: The visible lines should be dark heavy and dark lines. It shows the outline and shape of the object. It defines you can see in particular view.

2) Hidden lines: The hidden lines should be light, narrow, short and dashed lines. It shows the outline of a feature that cannot see in particular view. It used to help Clarify feature.

3) Section lines: Thin line usually drawn at 45 degrees angle and it indicates the material that has been cut through in sectional view. This will also help us on net ionic equation calculator

4) Center Lines: The center lines are nothing but thin line consisting of long and short distances. It shows the center of holes, slots, paths of rotation and symmetrical objects.

5) Dimension lines: In alphabet of lines the dimension lines is nothing but lines dark and heavy lines. It shows the length , width , and height of the features of an object. It terminated with arrow heads

6) Extension lines: In alphabet of lines extension lines used to show the starting and stopping points of a dimension and it must have at least a 1/16 space between the object and the extension line.

7) Leader lines: In alphabet of lines leader lines should be thin lines and used to show the dimension or a note that is too large to be placed beside the feature .

8) Cutting plane lines: In alphabet of lines cutting plane lines is thick broken line that is terminated with short 90 degree arrow heads.

9) Break lines: In alphabet of lines break lines is used to break out sections for clarity or for shortening a part.

What does arithmetic mean?

In this section let me help you on what is arithmetic mean.
Definition for Arithmetic mean:

In mathematics and statistics, the arithmetic mean (or simply the mean) of a list of numbers is the sum of all of the list divided by the number of items in the list. If the list is a statistical population, then the mean of that population is called a population mean.

Steps to Find out the Mean:

1. Add all the numbers (on a scratch piece of paper if needed.)

2. After we have added the numbers correctly, count how many numbers there are
(for example: 2, 3, 5, 4, 1 there are 5 numbers, right.)

3. Now divide the integer of how many of the numbers you have by the sum
(For example: 20(sum) divided by 5,(how many of the numbers) the answer would by 4). This can also help us on homework now

Formulas for Arithmetic Mean

Grouped Data Arithmetic Mean Definition:
Data arising from organizing n observed values into a smaller number of disjoint groups of values, and counting the frequency of each group; often presented as a frequency table.

Formula:

Grouped Data Arithmetic Mean :
Arithmetic Mean = ΣfX / Σf
where
X = Individual score
f = Frequency
