The stationary point of y=sinx are​

Answer»

Given :   y = Sinx

To find :  STATIONARY point

Solution:

The stationary points will be the points where the gradient   is zero:

y = sinx

dy/dx  =  Cosx

Cosx = 0   for    x  = (2n + 1)π/2   n ∈ Z  

n = 0 => Sinπ/2  = 1   = (-1)⁰

n = 1 => Sin3π/2  = -1  = (-1)¹

n = 2 => Sin5π/2  =  1   = (-1)²

Sin ( (2n + 1)π/2 )  =   (-1)ⁿ

Hence stationary  point is    (  (2n + 1)π/2  ,  (-1)ⁿ )

Banshali bought two radios for Rs800. She sold them to gain 10% on one and loss 10% on another. Find the gain or loss if SP of both the radio is same​

Answer»

Step-by-step EXPLANATION:

The CP of First radio is 800

then it is sold for 10% GAIN = 800*10/100 =80

therefore SP would be 800+80 = 880

The SP of 2ND radio would be ( LOSS of 10%/

SP = CP - loss

= 800-80

= 720

The total COST of both the radios is 800+800= 1600

SP of both the radios is 880+720 =1600

CP= SP

therefore there is no profit or no loss

The two positive numbers whose sum is 12 and sum of the squares in minimum are​

Answer»

Answer: The numbers are 7.5 and 7.5.

Step-by-step EXPLANATION:

LET the first number is x,

SINCE, the sum of two number is 15,

⇒ First number + second number = 15,

⇒ x + second number = 15

⇒ Second number = 15 - x

Let f(x) shows the sum of the squares of the number,

⇒ f(x) = x² + (15-x)² = 2x²- 30x + 225,

By differentiating with respect to x,

We get,

f'(x) = 4X - 30,

For maximum or minimum, f'(x) = 0,

⇒ 4x - 30 = 0 ⇒ x = 7.5,

Again differentiating f'(x) with respect to x,

f''(x) = 4

At x = 7.5 f''(x) = Positive,

Thus, f(x) is minimum at x = 7.5,

Hence, the first number is 7.5,

And, the second number is 15 - 7.5 = 7.5

If a+ib/c+id=x+iy prove that X²+y²=a²+b²/c²+d²​

Answer»

Answer:

LHS = RHS

Step-by-step EXPLANATION:

 Here,

⇒ ( a + bi ) / ( c + ID ) = x + iy

 Using the properties of complex NUMBERS, we know :  

  if z = a / d  then  | z | = | a | / | d |    where z, a , d are  complex numbers.

Using the same property;

 Modulus of LHS = Modulus of RHS

\implies \mathrm{\bigg| \dfrac{a+bi}{c+di} \bigg| =|x+iy|}

\implies \mathrm{\dfrac{\sqrt{a^2+b^2}}{\sqrt{c^2+d^2 } }=\sqrt{x^2 +y^2}}\\\\\\\implies \mathrm{\dfrac{a^2 +b^2}{c^2+d^2}=x^2+y^2 }

LHS = RHS
