-x + y = 8
podryga [215]

Answer:

No solution

Step-by-step explanation:

-x + y = 8..............(1)

1/2x - 1/2y = 3......(2)

Multiply (2) by 2

x - y = 6 ............(3)

Adding (1) and (3)

-x + x + y - y = 8 + 3

x and y are both eliminated so no solution

Can y = sin(t2) be a solution on an interval containing t = 0 of an equation y + p(t) y + q(t) y = 0 with continuous coefficient
JulsSmile [24]

Answer:

Step-by-step explanation:

y = sin(t^2)

y' = 2tcos(t^2)

y'' = 2cos(t^2) - 4t^2sin(t^2)

so the equation become

2cos(t^2) - 4t^2sin(t^2) + p(t)(2tcos(t^2)) + q(t)sin(t^2) = 0

when t=0, above eqution is 2. That is, there does not exist the solution. so y can not be a solution on I containing t=0.
