calculating ratios

In this blog let us learn about calculating ratios,in arithmetic, a ratio expresses the magnitude of quantities relative to each other. Specifically, the ratio of one quantities indicates how plenty of times the first quantity is contained in the second & may be expressed algebraically as their quotient.We can get a clear picture about calculating ratios with the help of an example problem of a inverse ratio,

Ex 2:

Solve

Sol:

=

= (numerator and denominator are divided by 10)

=

Answer is 2 by 3 or 2:3.

In the next Blog we will learn about algebra rules and also about geometry calculator,hope you like the above example of calculating ratios,please leave your comments if you have any doubts.

find percentage

In this blog we will learn how to find percentage,we can learn about this with the help of an example problem,Find the percentage of math students out of 50 students if only 34 are from mathematics department.
Given that
Total number of students = 50
Math students = 34
Percentage of math students = (34/50) x 100
= 34 x 2
= 68
There are 68% of math students.This is one of the methods to Find the percentage of math students out of 50 students if only 34 are from mathematics department.
Given that

= 34 x 2
= 68
There are 68% of math students.This is one of the methods to find percentage,next we will learn about elementary statistics,in statistics, the mean, median, range, and mode these are very important and very simple terms in the elementary statistics.In the next blog we will learn about geometric formulas.
Hope you like the ab0ve example of find percentage,please leave your comments if you have any doubts.

what is differentiation

In this blog let us learn about what is differentiation,Differentiation means discriminating any two things into different and distinct and define as the rate of change of a function with respect to one of its variable.Definition of simple differentiation.Simple differentiation defines as how a function changes with respect the other variable. Which is usually expressed as 'delta' change.Differentiation is known as the process to compute the rate at which a dependent output y changes with respect to the change in the independent input x.This pace of change is known as the derivative of y with respect to x. In lay mans terms the relying factor of y upon x means that y is a function of x.This functional relationship is often signified as y = ƒ(x), where ƒ denotes the function. If x and y are real numbers,and if the graph of y is marked against x, then derivative measures the slope of this graph at each point.If the student learns the various processes it helps them to learn how to write numbers,in the next blog we will learn about properties of multiplication,hope you like the above example of what is differentiation,please leave your comments if you have any doubts.

Using math logarithms

Welcome to math tutors online,
We need to talk about logarithms. Say you have 2^x = 64
(2^x is my way of saying "2 raised to the x power"), and you want to
solve for x.

Well, we know that
64 = 2*32 = 2*(2*16) = 2*2*2*8 = 2*2*2*2*2*2 = 2^6, so x = 6.

How about 2^x = 5? There we're stuck, because 2^2 = 4 and 2^3 = 8
so x should be somewhere between 2 and 3 to make 2^x = 5.

There's another way of saying what x should be, and this is called the
logarithm of 5 to the base 2. examples on free math; That is, x = log[2](5); (the 2 should be
a subscript, like a power but typed a bit below the log, so it isn't
log 10). In general, the solution to b^x = n for some given b and n is
x = log[b](n). b is called the *base* of the logarithm.

Engineering calculations

Greetings from math tutor online free,

Engineers really do carry out some of these types of calculations, but
the mathematics textbooks tend to simplify the problems quite a bit
(which is not necessarily a bad thing; examples on free math; this type of problem really
does illustrate how specific mathematical concepts are applied to
other fields.)

For engineers in the world, the support column
mentioned above might also need to hold 28 tons after it is eighty
years old, has been crashed into by three cars and a truck, and has
survived four earthquakes and one flood. Now how would you calculate
the diameter? By the way, don't forget that the concrete at the
bottom of the column also needs to hold the weight of the column
itself in addition to the 28 ton 'load'. learn more on math helper.
