Question

Determine order and degree (if defined) of differential equation:-
$\sf{\frac{d^{4}y}{dx^{4}}+\sin(y''')}$

Answer 1

Answer:

Join A to the centre O of the circle. This line splits the angle at A into two parts, x° and y° .

● Here Δ AOB and Δ AOC are isosceles triangle

Thus, ∠ ABO = ∠ OAB = x° and ∠ ACO = ∠ OAC = y°

● Let us take ∠ BOC = c°

⇒ (180° – 2x) + (180° – 2y) + c° = 360°

⇒ 360° –2 (x+y) +c° = 360°

⇒ 2(x+y) = c°

Answer 2

Step-by-step explanation:

$Higher \: \\ order \: is \: \\   d 4 y \: d x 4 \: d4ydx4  \: so \: \\ order \: is \: 4 \: As \: it \: is \: \\ not \: a \: polynomial \: in  \: d y d x \: dydx \: \\  degree \: is \: not \: defined.$
