                                        Ans:$I = \int \frac{2x^{2}-3x+8}{2x^{3}-4x^{2}+8x-1}dx$We will proceed this question by partial fraction rule.$f(x) = 2x^{3}-4x^{2}+8x-1$Roots of f(x):$x_{1} = .1333$$x_{2} = .93335+1.69707i$$x_{3} = .93335-1.69707i$$\frac{2x^{2}-3x+8}{2x^{3}-4x^{2}+8x-1} = \frac{a}{x-x_{1}} + \frac{b}{x-x_{2}}+\frac{c}{x-x_{3}}$We have values of a, b & c from here,$I = \int (\frac{a}{x-x_{1}}+\frac{b}{x-x_{2}}+\frac{c}{x-x_{3}})dx$$I = aln|x-x_{1}| + bln|x-x_{2}| + cln|x-x_{3}| + constant$Thanks & RegardsJitender SinghIIT DelhiaskIITians Faculty

A VECTOR OF MAGNITUDE ‘a’ IS ROTATED THROUGH ANGLE THETA.WHAT IS THE MAGNITUDE OF THE CHANGE IN THE VECTOR?

Dear Bharat As the vector has been rotated by angle theta, Let the final vector be called as v f , while the initial being v i The magnitude of change in vector is | v f – v i | = ( v i 2 + ...

f(0)=f(1)=0,f / (1)=2 &y=(e x )e f(x) dy/dx=

let, g’(0)=f’(1)e f(0) +f(1)e f(0) .f(0) =f’(1)+f’(0)=0+2=2
