8-2root5 contradiction method​

Answer»

<P>Answer:

let the GIVEN number is rational number

so, 8-2√5 =p/q                            {where q≠0}

-2√5 =p/q  -8  

2√5 =   -p/q  +8  

2√5 = (8q -p)/q

√5 = (8q -p)/2q

here , (8q -p)/2q is a rational number but it is EQUAL to IRRATIONAL number

so, it is a irrational number

If alpha and beta are the zeroes of the polynomial f(x)= x^2 + px +q form a polynomial whose zeroes are (α+β)^2 and (α - β )^2​

Answer»

Answer:

We have polynomial  f ( x ) =  x2  + p x  + Q

And

Roots are α  and β

And

we KNOW from relationship between zeros and COEFFICIENT

Sum of zeros  = −Coefficient of xCoefficient of x2

So,

α  + β  =  - p                                         ------ ( 1 )

Taking whole square on both hand side , we get

( α  + β  )2 = p 2                                  ------ ( 2 )

⇒α2 + β2 +  2 α β = P2⇒α2 + β2 +  2 α β − 2αβ + 2αβ=  p2⇒α2 + β2 −  2 α β  +4 αβ=  p2⇒(α  − β) 2  +4 αβ=  p2                     −−−− ( 3 )

And

Products of zeros  = Constant termCoefficient of x2

So,

α  β  =  q        , Substitute that value in equation 3 , we get

⇒(α− β)2 +  4 (q ) = p2⇒(α− β)2 +4 q=  p2⇒(α− β)2  = p2 − 4 q              −−−− ( 4 )   

Now we add equation 2 and 4 and get

(α + β)2 + (α − β)2 = p2 +  p2 − 4 q= 2 p2 − 4 q

And we multiply equation 2 and 4 and get

(α + β)2 × (α − β)2 = p2( p2 − 4 q)= p4 − 4 p2q

And we know formula for polynomial when sum of zeros and product of zeros we know :

Polynomial  =  k [ x2  - ( Sum of zeros ) x  + ( Product of zeros ) ]   , Here k is any NON zero real number.

Substitute values , we get

Quadratic polynomial  =  k [ x2  - ( 2 p2 - 4 q) x  + ( 2 p4 - 4 p2q) ] 

                             

= x2  - ( 2 p2 - 4 q) x  + ( 2 p4 - 4 p2q) [ taking k = 1 ]                                         ( Ans )

Exponential function versus arithmetic function

Answer»

                           EXPONENTIAL FUNCTION

In addition to linear, quadratic, rational, and radical functions, there are exponential functions. Exponential functions have the form f(x) = bx, where b > 0 and b ≠ 1. Just as in any exponential expression, b is called the base and x is called the exponent.

 

An example of an exponential function is the growth of bacteria. Some bacteria double every hour. If you start with 1 bacterium and it doubles every hour, you will have 2X bacteria after x hours. This can be written as f(x) = 2x.

 

Before you start,   f(0) = 20 = 1

After 1 hour           f(1) = 21 = 2

In 2 hours              f(2) = 22 = 4

In 3 hours              f(3) = 23 = 8

and so on.

 

With the definition f(x) = bx and the restrictions that b > 0 and that b ≠ 1, the domain of an exponential function is the set of all real numbers. The range is the set of all positive real numbers. The following graph shows f(x) = 2x.

                              ARITHMETIC FUNCTION

A complex-valued function, the domain of definition of which is one of the following sets: the set of natural numbers, the set of rational integers, the set of integral ideals of a given algebraic number field, a lattice in a multi-dimensional coordinate space, etc. These are arithmetic functions in the wide sense. However, the term is often employed to denote a function of the above type with special arithmetic properties. The most commonly occurring arithmetic functions have traditional SYMBOLIC notations: ϕ(n) is the Euler function; d(n) or τ(n) is the number of divisors; μ(n) is the Möbius function; Λ(n) is the Mangoldt function; σ(n) is the sum of divisors of the number n. Arithmetic functions also include the integral part of a number, [x], and the FRACTIONAL part of a number, {x}. Arithmetic functions giving the number of solutions of an equation are also studied; for example, r(n) is the number of integer solutions x and y of the equation x2+y2=n in the Goldbach problem; J(N) is the number of solutions in prime numbers of the equation N=p1+p2+p3. Other arithmetic functions express the quantity of numbers satisfying certain conditions; thus, for instance, the function π(x) — the number of primes not larger than x — describes the distribution of primes; π(x,q,l) gives the number of primes not larger than x in the arithmetic progression p≡l(modq). The Chebyshev functions also deal with properties of primes: θ(x) is the sum of the natural logarithms of the prime numbers up to x, while ψ(x)=∑n≤xΛ(n) (cf. Chebyshev function).

Algebraic number theory deals with generalizations of the above arithmetic functions of a natural argument. Thus, for instance, in an algebraic field K of degree n, Euler's function ϕ(U) — the number of residue classes by the ideal U mutually prime with U — is introduced for an integral ideal U.

Arithmetic functions appear and are employed in studies on the properties of numbers. However, the theory of arithmetic functions is also of independent interest. The laws governing the variations of arithmetic functions cannot usually be described by simple formulas, and the asymptotic behaviour in terms of numerical functions is determined. Since many arithmetic functions are not monotone, the study of their average values is of great importance (cf. Average order of an arithmetic function). An important class of arithmetic functions is constituted by the multiplicative arithmetic functions and the additive arithmetic functions. The problem of the distribution of their values is studied in probabilistic number theory [5].

Prove tan (45+a) = cos2a / 1-sin2a

Answer»

Answer:Proved

Step-by-step explanation:tan(π/4+a)

tan(a+b)=tan a+tan b/(1-tan a tan b)

tan(π/4+a)=tan π/4+tan a/1-tan π/4 tan a

tan(π/4+a)=1+tan a/1-tan a

tan(π/4+a)=(1+sin a/cosA)/(1-sin a/COS a)

tan(π/4+a)=(cos a+sin a)/(cos a-sin a)

RATIONALISING, we GET

(cos a+sin a)(cos a-sin a)/(cos a-sin a)(cos a-sin a)

cos²a-sin²a/(cos a-sin a)²

cos 2a/(cos²a+2sin a cos a+ sin²a)

Since cos²a+sin²a=1

cos 2a/1-sin 2a

The sum fo 4th and 8th term =22and the product of 2nd and 6th term =33.Find AP?​

Answer»

GIVEN,

☛ sum of 4th term and 8th term = 22

==> a + 3d + a + 7d = 22

==> 2a + 10d = 22

==> a + 5D = 11 ...(1), ALSO, It is the 6th term)

Also,

product of 2nd term and 6th term = 33

==> ( a + 5d ) * (a + d) = 33

==> 11(a + d) = 33

==> a + d = 3

==> d = 3 - a ...(2)

PUTTING d = 3 - a in (1)

==> a + 5(3 - a) = 11

==> a + 15 - 5a = 11

==> -4a = -4

==> a = 1 ...(3)

Putting a = 1 in (2)

==> d = 3 - a

==> d = 3 - 1

==> d = 2 ...(4)

A.P = a , a + d, a + 2d, a + 3d, ...

A.P = 1 , 3, 5, 7, 9, ...
