Question

xdx+ydy/xdx-ydy=(a^2-x^2-y^2)^1/2/(x^2+y^2)^1/2 solve the differentions eqution

Answer 1

Can you use the equation button below

Answer 2

Yea

Answer 3

\[x^2 + y^2 = r\]
\[x = rcos\theta\]
\[y=rsin\theta\]

Answer 4

\[tan \theta = \frac{y}{x}\]

Answer 5

Now\[xdx + ydy=rdr\]

Answer 6

\[d(\frac{y}{x}) = d(tan\theta)\]

Answer 7

I am sorry I can't get it

Answer 8

I can't get denominator in the equation if it had been xdy - ydx then I would have done that
