    (1-x) y"-4xy'+5y=cosx

    = Second order

    = linear

    2. t^5 y^ (4) - t^3 y" + 6y = 0

    = Second order

    = non linear

    3. (d^2Y/dx^2) = sqrt ((1 + (dy/dx) ^2))

    = Second order

    = Linear

    4. (Sinθ) y"' - (cosθ) y' = 2

    = Third order

    = Non linear

    Step-by-step explanation:

    (1-x) y"-4xy'+5y=cosx

    = Second order

    = linear

    2. t^5 y^ (4) - t^3 y" + 6y = 0

    = Second order

    = non linear

    3. (d^2Y/dx^2) = sqrt ((1 + (dy/dx) ^2))

    = Second order

    = Linear

    4. (Sinθ) y"' - (cosθ) y' = 2

    = Third order

    = Non linear
