प्रश्न

Evaluate : `∫(sin^6x+cos^6x)/(sin^2x.cos^2x)dx`

Advertisements

उत्तर

`int(sin^6x+cos^6x)/(sin^2x.cos^2x)dx`

`=int((sin^2x+cos^x)^2-3sin^2x.cos^2x(sin^2x+cos^2x))/(sin^2x.cos^2x)dx  [Using a^3+b^3=(a+b)^3−3ab(a+b)]`

`=int(1-3sin^2x.cos^2x)/(sin^2xcos^2x)dx [Using sin^2x+cos^2x=1]`

 `=int(1/(sin^2x.cos^2x)-3)dx`

`=int((sin^2x+cos^2x)/(sin^2x.cos^2x)-3)dx`

`=int(sec^2x+cosec^2x-3)dx`

`=intsec^2xdx+intcosec^2xdx-int3dx`

`=tanx-cotx-3x+C`
