Question

solve the differntial equation:
(D2+2D+1)y=exp(x)tanx

Answer 1

please reply

Answer 2

this means \[y''+y'+y=e^x \tan(x)\]

Answer 3

u need to find homogeneous solution and particular solution, do u know how?

Answer 4

i know but dont know how to tackle tanx in this

Answer 5

yea forget tan(x) for now, find the homogeneous solution
homogeneous solution is when y''+y'+y=0

Answer 6

that i know,i want to find its particular soln

Answer 7

do u know variation of parameters method?

Answer 8

ya

Answer 9

i am trying that method but u know any other method also??
