13.	P.t.: cos³2x +3cos2x= 4(cos^6x-sin^6x)
Answer» we have to prove that, cos³(2x) + 3cos(2x) = 4(cos^6x - sin^6x) LHS = cos³(2x) + 3cos(2x) we know, cos2x = 2cos²x - 1 then, cos³(2x) + 3cos(2x) = (2cos²x - 1)³ + 3(2cos²x - 1) = (2cos²x)³ - 3(2cos²x)² + 3(2cos²x).1² - 1 + 6cos²x - 3 = 8cos^6x - 12cos⁴x + 6cos²x + 6cos²x - 4 = 8cos^6x - 12cos⁴x + 12cos²x - 4 = 8cos^6x - 12cos²x(cos²x - 1) - 4 = 8cos^6x - 12(1 - sin²x) sin²x - 4 = 4cos^6x + 4cos^6x - 12sin²x + 12sin⁴x - 4 = 4cos^6x + 4(1 - sin²x)³ - 12sin²x + 12sin⁴x - 4 = 4cos^6x + 4(1 - 3sin⁴x + 3sin²x - sin^6x) - 12sin²x + 12sin⁴x - 4 = 4cos^6x + 4 - 12sin⁴x + 12sin²x - 4sin^6x - 12sin²x + 12sin⁴x - 4 = 4cos^6x - 4sin^6x = 4(cos^6x - sin^6x) = RHS

13.

P.t.: cos³2x +3cos2x= 4(cos^6x-sin^6x)

Answer»

we have to prove that,

cos³(2x) + 3cos(2x) = 4(cos^6x - sin^6x)

LHS = cos³(2x) + 3cos(2x)

we know, cos2x = 2cos²x - 1

then, cos³(2x) + 3cos(2x) = (2cos²x - 1)³ + 3(2cos²x - 1)

= (2cos²x)³ - 3(2cos²x)² + 3(2cos²x).1² - 1 + 6cos²x - 3

= 8cos^6x - 12cos⁴x + 6cos²x + 6cos²x - 4

= 8cos^6x - 12cos⁴x + 12cos²x - 4

= 8cos^6x - 12cos²x(cos²x - 1) - 4

= 8cos^6x - 12(1 - sin²x) sin²x - 4

= 4cos^6x + 4cos^6x - 12sin²x + 12sin⁴x - 4

= 4cos^6x + 4(1 - sin²x)³ - 12sin²x + 12sin⁴x - 4

= 4cos^6x + 4(1 - 3sin⁴x + 3sin²x - sin^6x) - 12sin²x + 12sin⁴x - 4

= 4cos^6x + 4 - 12sin⁴x + 12sin²x - 4sin^6x - 12sin²x + 12sin⁴x - 4

= 4cos^6x - 4sin^6x

= 4(cos^6x - sin^6x) = RHS

32.	Find root x-1/x=3,xis not equal to 0
Answer» Given: x - 1/x = 3 , x is not equal to 0. To FIND out: Find the ROOT of given EQUATION? Solution: We have, x - 1/x = 3 Multiplying throughout by x the given equation can be written as x² - 1 = 3x => x² - 3x - 1 = 0 Which is a quadratic equation. ( a = 1 , b = -3 , c = -1 ) So, D = b² - 4ac = ( -3 )² - 4 × 1 × (-1) = 9 + 4 = 13 [ 13 > 0 ] We KNOW that, x = -b ± √D/2a = -3 ± √13/2 × 1 = 3 ± √13/2 So, the roots are 3 + √13 / 2 and 3 - √13 / 2.

32.

Find root x-1/x=3,xis not equal to 0

Answer»

Given:

x - 1/x = 3 , x is not equal to 0.

To FIND out:

Find the ROOT of given EQUATION?

Solution:

We have,

x - 1/x = 3

Multiplying throughout by x the given equation can be written as

x² - 1 = 3x => x² - 3x - 1 = 0

Which is a quadratic equation.

( a = 1 , b = -3 , c = -1 )

So,

D = b² - 4ac

= ( -3 )² - 4 × 1 × (-1)

= 9 + 4

= 13 [ 13 > 0 ]

We KNOW that,

x = -b ± √D/2a

= -3 ± √13/2 × 1

= 3 ± √13/2

So, the roots are 3 + √13 / 2 and 3 - √13 / 2.

35.

A has got 20% more marks than b then by what percent marks of b are less than the marks of a?

Answer»

LET marks of B = x

Marks of A will be = x + 20% of x = x + 20x/100 = 120x/100

Marks of B are less than A by A-B/A * 100

= {(120x/100 - x) / (120x/100)} * 100

= {(20x/100) / (6x/5)} * 100

= {(x/5) / (6x/5)} * 100

= 5/30 * 100

= 50/3 = 16.66%
