Find two independent solutions for t0 of the associated homo
Find two independent solutions (for t>0) of the associated homogeneous equation t^2x\'\'-2tx+2x=0 of the form x=the for a constant m.
Find two independent solutions (for t>0) of the associated homogeneous equation t^2x\'\'-2tx+2x=0 of the form x=the for a constant m.
Solution
t2x\'\'-2tx+2x=0 { y= erx & y\' = r erx & y\"= r2 erx}
So,
t r2 erx - 2t erx + 2 erx = 0
erx ( t r2 - 2t +2 )=0
but ( t r2 - 2t +2 ) cant be \'0\' so erx is equals to 0
( t r2 - 2t +2 ) = 0
t ( r 2 -2) +2 =0
t ( r 2 - 2) = -2
( r 2 -2) = -2 / t
for t > 0 put any value of t which is greater than 0 so put 1 and 2
for r1 , put t= 1
( r 2 -2)= - 2/1
r 2 = -2 + 2
r1=0
for r2 , putt= 2
( r 2 -2)= - 2/2
( r 2 -2)= - 1
r 2 = -1 + 2
r2 = 1
r2 = 1
For independent homogenous equation
= C1er1x + C2er2x
= C1e0 x+ C2e1x
= C1e0 x+ C2e1x
= C1 + C2ex ans...
