| solve partial differantial equation x((∂f(x,y))/∂x)+y((∂f(x,y))/∂y)=f(x,y)ln(x^2 +y^2 ) ((∂^2 f(x,y))/∂x^2 )+((∂^2 f(x,y))/∂y^2 )=0 |

| let′s define linear differantial operator D as D=z∙((d )/dz)(z∙((d )/dz))+z(1−((α/z))^2 ) when Df(z)={z∙((d )/dz)(z∙((d )/dz))+z(1−((α/z))^2 )}f(z)=0 f(z)=? |
| 1) The function H is defined by H(x) =3cosh(x/3)+sinh(x/3). Find the value of λ for which H(lnλ^3 )=4 2) Prove that ∫_2 ^4 ((6x+1)/((2x−3)(3x−2)))dx= ln 10. 3)Show that ((sinθ + sin2θ)/(1+ cosθ+ cos2θ))≡ tanθ 4) If z=cosθ+ i sinθ, Show that z+(1/z)=2cosθ and that z^n +(1/z^n )=2cos nθ hence or otherwise show that 32cos^6 θ= cos 6θ +6cos 4θ + 15cos 2θ+ 10.
