Question

find wroskian without solving
(cost)y''+(sint)y'-ty=0

Answer 1

first find aux. eqn
you need that to find your wronskian

Answer 2

diff EQ... find roots first right. I'm learning this right now too. so \[\cos(t)r ^{2}+ \sin(t)r-t\]

Answer 3

yes

Answer 4

now what lol

Answer 5

cant have t , you will not be able to solve that with that t in it

Answer 6

but that is the wroskian equation.

Answer 7

it should be an eqn in term of R only

Answer 8

in my notes the y without prime is just dropped and the coefficient is carried forward

Answer 9

r^2+r-1
find its roots, then find y' and y" that will give you a hint for your wronskian

Answer 10

r=+1, -1 ; but aren't you supposed to carry the coefficients with you into the wronskian equation

Answer 11

my roots are wrong. you can't get the roots of what you wrote

Answer 12
