3 Dimentional Figures

3 dimensional figures:
Find the surface area of the cylinder when the area of the cylinder is 157 cm² and the radius and height is 5 cm and 7 cm respectively.
Given: Area = 157 cm²
Radius = 5 cm
Height = 7 cm
Sol:
Formula: 2Пr² + 2Пrh = 157 + 2П5(7) =157 + 219.8 = 376.8 cm^{2

The accepted representation of cast is m [xx] n area the capricious m shows amount of rows in the accustomed cast and the capricious n denotes amount columns in the accustomed matrix.
When the amount of rows of the aboriginal cast is according to amount of columns of the additional cast agency alleged as according matrix. In multiplication accumulate every row of aboriginal cast assorted with every cavalcade of additional matrix. The accumbent adjustment of adjustment is alleged as row matrix. The vertical adjustment of adjustment elements is alleged as cavalcade matrix.
The afterward action is followed at the time cast multiplication
Accumulate the row of aboriginal cast with cavalcade of additional matrix.
We can add aboveboard cast with non aboveboard matrix. Aboveboard cast has according amount of rows and according amount of columns.

Factors are the digit that is multiplied equally to get another number:
3 x 7 = 21 (3, 7 factor)
In prime factorization, every factor will be prime numbers.
Example:
The prime factors of 21 will be 3 and 7 (3 x 7 = 21, and 3 and 7 are prime numbers).

Introduction to calculus

Introduction to calculus:

Here the function f(x) = (x + 5) have the following conditions,
(x + 2)
At point zero, we can say that numerator = 0
So, x+5 = 0 => x=-5.
At vertical asymptote at x=-2, since denominator = 0
x+2 = 0 => x=-2
At y-intercept, the function of x equal zero, then
f(x) = 0, (0 + 5) = 5

Introductory Algebra

introductory algebra:

In intermediate algebra and in other branches of arithmetic, letters are used to represent numbers with unknown or unassigned values.

A number represented by a letter is called a literal number, and any number expression in which one or more number symbols are letter is called a literal expression.

In any number expression the parts connected by the signs + or - are called terms. An expression by either of the signs + or – consists of one terms, and is called a monomial. An expression consisting of two terms is a trinomial. In general, an expression consisting of three or more terms is called a polynomial in intermediate algebra.
