D*2-2d+1)y=xlogx using the method of variation parameters ;where d=d/dx

Answer»

Given :   (D² - 2D + 1)y = x log x

To find : solve for y

Solution:

(D² - 2D + 1)y = x log x

=> y'' - 2Y' + y = x log x

let say log x = t   => x =  e^{t}

DX =   e^{t}dt

y'' - 2y' + y =   t .e^{t}

=> (y''  - 2y'  + y)e^{-t}   = t

=> (y''  - y'    - y'  + y)e^{-t}    = t

=> (y''  - y')e^{-t}   - (y'  - y)e^{-t}    = t

=>  (y'e^{-t}  )'   -  (ye^{-t} )' = t

integrating both sides

 (ye^{-t} )' =  t²/2  + C

integrating again

 ye^{-t}    =  t³/6  + Ct + D

=> y =   e^{t}  ( t³/6  + Ct + D )

Substitute x =  e^{t}   and log x = t

y =    x  ( (log x)³/6  + Clog(x) + D )

Integration of cos4x*cos5x*sin2x​

Answer»

Given : ∫cos4x cos5x sin2xdx

To Find : Integrate

Solution:

I =   ∫cos4x cos5x sin2xdx

Simplify cos4x cos5x sin2x

= 2cos5x cos4x sin2x /2

2Cosacosb = Cos(a - b) + Cos(a + b)

= ( Cosx + cos 9x)sin2x/2

= Cosxsin2x/2  + cos9xsin2x/2

sin2x = 2sinx.cosx

= Cosxsinx.cosx  + cos9xsin2x/2

= cos²xsinx  + 2sin2xcos9x/4

2sinacosb  = sin(a + b) + sin(a - b)

= cos²xsinx  + {Sin11x  + sin(-7X)}/4

= cos²xsinx  + {Sin11x  -  sin(7x)}/4

= cos²xsinx  + Sin11x/4  - Sin7x/4

I = ∫ cos²xsinx  + Sin11x/4  - Sin7x/4) DX

=  ∫(cos²xsinxdx  +(1/4) ∫Sin11x .dx  - (1/4) ∫Sin7x dx

∫(cos²xsinxdx  

cosx = y ,  -sinxdx = dy  

=> -∫y²dy   =  - y³/3  + C   =      -cos³x /3  + c

(1/4) ∫Sin11x .dx  - (1/4) ∫Sin7x dx

= (1/4) -Cos11x/11  -(1/4)(-cos7x)/7  + c

I =   -cos³x /3  - cos11x /44  + Cos7x/2x + C
