해법

을 위해 해결하다

y, f = - \frac{40000 x}{( 3 + x ^{2} + 2 y ^{2} ) ^{2}}

y = \frac{f 40000 x + 9 f + x ^{4} f + 6 x ^{2} f}{2 f} cos \frac{arctan ( - \frac{200 x f}{f ( 3 + x ^{2} )} )}{2} + i \frac{f 40000 x + 9 f + x ^{4} f + 6 x ^{2} f}{2 f} sin \frac{arctan ( - \frac{200 x f}{f ( 3 + x ^{2} )} )}{2}, y = \frac{f 40000 x + 9 f + x ^{4} f + 6 x ^{2} f}{2 f} cos \frac{arctan ( - \frac{200 x f}{f ( 3 + x ^{2} )} ) + 2 π}{2} + i \frac{f 40000 x + 9 f + x ^{4} f + 6 x ^{2} f}{2 f} sin \frac{arctan ( - \frac{200 x f}{f ( 3 + x ^{2} )} ) + 2 π}{2}, y = \frac{f 40000 x + 9 f + x ^{4} f + 6 x ^{2} f}{2 f} cos \frac{arctan ( \frac{200 x f}{f ( 3 + x ^{2} )} )}{2} + i \frac{f 40000 x + 9 f + x ^{4} f + 6 x ^{2} f}{2 f} sin \frac{arctan ( \frac{200 x f}{f ( 3 + x ^{2} )} )}{2}, y = \frac{f 40000 x + 9 f + x ^{4} f + 6 x ^{2} f}{2 f} cos \frac{arctan ( \frac{200 x f}{f ( 3 + x ^{2} )} ) + 2 π}{2} + i \frac{f 40000 x + 9 f + x ^{4} f + 6 x ^{2} f}{2 f} sin \frac{arctan ( \frac{200 x f}{f ( 3 + x ^{2} )} ) + 2 π}{2}; f \neq = 0

솔루션 단계

f = - \frac{40000 x}{( 3 + x ^{2} + 2 y ^{2} ) ^{2}}

양쪽을 곱한 값

(3 + x^{2} + 2 y^{2})^{2}

f (3 + x^{2} + 2 y^{2})^{2} = - 40000 x

f (3 + x^{2} + 2 y^{2})^{2} = - 40000 x
