Question

Solve this differential equation by eliminating the arbitrary constants.
y=Acos(log x) + Bsin(log x)

Answer 1

the equation or differential equation?

Answer 2

diffrential eqn

Answer 3

but where are the differentials?

Answer 4

you have to eliminate A & B

Answer 5

i guess this is the prob to form a DE

Answer 6

Yea DE.

Answer 7

question makes no sense

Answer 8

eq contains 2 constants, differentiate twice n solve

Answer 9

how this makes no sense? this is que from book. @ elecengineer

Answer 10

Yea But M unable to solve.can u help me in differentiating?

Answer 11

y'=-Asin(logx)(1/x)+Bcos(logx)(1/x)
y''=-Acos(logx)(-1/x^2)-Bsin(logx)(-1/x^2)
=(1/x^2)[Acos(logx)+Bsin(logx)]
y''=(1/x^2)y

Answer 12

okay thank u so much uzma let me check

Answer 13
