Question

solve differential equations cos (dy /dx)=x​

Answer 1

Answer:

y(x)=x. acos(x)+C-√-x²+1

Answer 2

Correct Question:-

Find The Order And Degree:

$cos( \frac{dy}{dx} ) = x + y$

Step By Step Solution:-

$(\frac{dy}{dx}) {}^{2} = {cos}^{ - 1} (x + y)$

Order = Hight order derivative

Degree = Degree of highest order derivative.

Order = 1 ; Degree = 1
