Find the value of root x-1/root x if x= 2+root 3

Answer»

ANSWER :

√x - 1/√x = √6

SOLUTION :

Given : x = 2 + √3

To FIND : √x - 1/√x = ?

We have , x = 2 + √3

Thus ,

=> 1/x = 1/(2 + √3)

=> 1/x = (2 - √3) / (2 + √3)•(2 - √3)

=> 1/x = (2 - √3) / [ 2² - (√3)² ]

=> 1/x = (2 - √3) / (4 - 3)

=> 1/x = (2 - √3) / 1

=> 1/x = 2 - √3

Now ,

=> (√x - 1/√x)² = (√x)² - 2•√x•(1/√x)+(1/√x)²

=> (√x - 1/√x)² = x + 2 + 1/x

=> (√x - 1/√x)² = 2 + √3 + 2 + 2 - √3

=> (√x - 1/√x)² = 6

=> (√x - 1/√x) = √6

Hence ,

√x - 1/√x = √6

Prove that Cos^4A-Sin^4A+1=2Cos^2A​

Answer»

Answer:

I LEARNED this from a friend. Hope it helps

Step-by-step explanation:

First, group the first two terms and factor it.

(cos^4A-sin^4A)+1=2cos^2A

(cos^2A-sin^2A)(cos^2A+sin^2A)+1=2cos^2A

Then, apply the Pythagorean identity which is  cos^2theta + sin^2theta=1 .

 

(cos^2A-sin^2A)(1)+1=2cos^2A

cos^2A-sin^2A + 1=2cos^2A

Then, group the second and last TERM at the left side of the equation.

cos^2A+(-sin^2A+1)=2cos^2A

cos^2A+(1-sin^2A)=2cos^2A

To SIMPLIFY the expression INSIDE the parenthesis, apply the Pythagorean identity again.

cos^2A+cos^2A=2cos^2A

2cos^2A=2cos^2A

Since left side simplifies to 2cos^2A which is the same term with the right side, hence it proves that the given equation is an identity.
