Assertion left parenthesis A right parenthesis colon If u equals log space open parentheses fraction numerator x squared plus y squared over denominator x minus y end fraction close parentheses then x squared u subscript x x end subscript plus 2 x y u subscript x y end subscript plus y squared u subscript y y end subscript equals negative 1

Reason left parenthesis bold R right parenthesis colon If u equals f left parenthesis x comma y right parenthesis  is a homogeneous function in x comma y of degree ' n ' then x squared u subscript x x end subscript plus 2 x y u subscript x y end subscript plus y squared u subscript y y end subscript equals n left parenthesis n minus 1 right parenthesis u

For such questions, we should know the formulas related to homogeneous equation. Before solving the equation, we have to see if the given function is a homegenous function. A homegenous function has same degree for all its terms.
