integration of exponential

Let us learn about integration of exponential


Integration of exponents is referred as the reverse process to differentiation. Integration is known as anti-differentiation. Integration of exponents is applied in many applications. Integration is applied to find the area between 2 curves & amount of work done, etc…Integration of exponential always deals with the exponential functions. Exponents are represented by the power of e. By differentiation of exponents you find the derivative of the mention exponential function, whereas by integration of exponential you find the exponential function whose derivative is called. This is known as the integration of exponential of the given exponential function.

biconditional

Let us learn about biconditional

If 2 simple statements “p” & “q” are connected by the connective

'if & only if', then the resulting compound statement is known the biconditional statement. Symbolically biconditional is represented by p<-> q.

A biconditional is referred as a truth function which is true only in the case that both parameters are true or both are false.
Symbolically, the biconditional is written as aób or aób
The biconditional function is frequently written as ``iff,'' meaning ``if and only if.''
It gets its name from the fact that it is really 2 conditionals in conjunction,

(a->b)V (b->a)

p value formula

Let us learn about p value formula

The p-value is referred as the area under the null distribution curve which is in bigger disagreement with the null hypothesis than the observed test statistics.
Best example, the hypothesis test for the mean is:

Imagine you have a large enough sample such that the central limit theorem holds & the mean is normally distributed then to test the null hypothesis H0: μ = Δ

find the test statistic “z” = (x Bar - Δ) / (sx / square root (n)) where “x” bar is the sample average
sx is the sample standard deviation
”n” is the sample size

The p value formula of the test is the area under the normal curve which is in agreement with the alternate hypothesis.

H1: μ > Δ; p-value is the area to the right of z
H1: μ < Δ; p-value is the area to the left of z
H1: μ ≠ Δ; p-value is the area in the tails is always greater than |z|

for a small test for the mean every thing is the same save the test statistic is a t statistic with n - 1 degrees of freedom. In such case the underlying distribution should be normal for this test to be valid.

numerical coefficient

Let us learn about numerical coefficient
The definition for the numerical coefficient are given below the following section,

• Other name for the numerical coefficient is coefficient.

Best example, a₁ x₁ + a₂ x₂ + a₃ x₃ +……………………. a_n x_n
In the above given example,

• a₁ a₂ a₃ are known as numbers.
• x₁ x₂ x₃ are known as the variables.

Find the numerical coefficient for the product of mentioned terms, (2x² + 3x + 2) (x + 1).
The mentioned problem for numerical coefficient is,
(2x² + 3x + 2) (x + 1)
Next step, we have to product the above mentioned functions,
(2x² + 3x + 2) (x + 1)
= 2x² (x) + 3x(x) +2(x) +2x² + 3x + 2
= 2x³ + 3x² + 2x + 2x² + 3x + 2
= 2x³ + 5x² + 5x+2
Hence, the numerical coefficient is present before the variables.
Numerical coefficient = 2, 5, 5, 2
Thus, this is the required solution for the numerical coefficient.

math dictionary algebra

Let us learn about math dictionary algebra

Math dictionary algebra is a branch of mathematics that deals in representing numbers through variables. math dictionary algebra also deals with symbols, relations, functions, and equations. Math dictionary algebra is a branch of mathematics that substitutes letters for numbers. An algebraic equation represents a scale, what is done on 1 side of the scale with a number is also done to the other side of the scale. The numbers are the constants.

Math dictionary algebra is a very useful to everybody especially to students, tutors, researchers & etc. math dictionary algebra for students explains over 600 common mathematical terms & math words in simple language. The math dictionary algebra is much more than a compilation of words & definitions. Math dictionary algebra has been organized to reflect the different areas of mathematics taught in elementary & junior high schools. Within each category are all the terms commonly used in this field of math education, concise definitions, & many best examples & illustrations. In addition, the last chapter provides instructions for basic operations & tables of commonly-used facts & equivalents.

Math dictionary algebra may be used effectively in a variety of ways. Math dictionary algebra would definitely be an often sought reference book in any grade 4–9 math classroom, but it offers much more than simple definitions. Math dictionary algebra’s clear style & inclusion of many strategies for success in problem solving make it well adapted for independent instruction.

permutations and combinations worksheet

Let us learn about permutations and combinations worksheet

In permutations without Repetition, you have to decrease the number of available selections every time. When you have n unlike things then you have to decrease one from the prior term for each time.
This is similar to n * (n-1) * (n-2)….
& if you are asked to select r things from n things, the combination is

n!

P (n, r) = ---------

(n-r)!

Combinations with Repetition for worksheet:
You require to do is change permutations formula to decrease it by how many customs the things could be in order but the order is not significant here.

n!

C (n, r) = ---------

r! (n-r)!

Combinations without Repetition for worksheet:
When you have n unlike things & to chose r things with repetition you have a formula

n+r-1

C (n, r) = -----------

r! (n-r)!
