(\partial)/(\partial x)(ln(3x^2+y^2+4))

Lösung

\frac{\partial}{\partial x} (ln (3 x^{2} + y^{2} + 4))

\frac{6 x}{3 x ^{2} + y ^{2} + 4}

Schritte zur Lösung

\frac{\partial}{\partial x} (ln (3 x^{2} + y^{2} + 4))

Behandle

y

als Konstante

Wende die Kettenregel an:

\frac{1}{3 x ^{2} + y ^{2} + 4} \frac{\partial}{\partial x} (3 x^{2} + y^{2} + 4)

= \frac{1}{3 x ^{2} + y ^{2} + 4} \frac{\partial}{\partial x} (3 x^{2} + y^{2} + 4)

\frac{\partial}{\partial x} (3 x^{2} + y^{2} + 4) = 6 x

= \frac{1}{3 x ^{2} + y ^{2} + 4} \cdot 6 x

Vereinfache

\frac{1}{3 x ^{2} + y ^{2} + 4} \cdot 6 x : \frac{6 x}{3 x ^{2} + y ^{2} + 4}

= \frac{6 x}{3 x ^{2} + y ^{2} + 4}

y^{^{''}} + 4 y^{^{'}} + 4 y = e^{- 2 x}

a re a x = 6 y^{2}, x = 4 + 2 y^{2}

t an g e n t f (x) = x (x^{6} - 1), at x = 1

\int e^{x} \cdot cos (3 x) d x

\int \frac{6 x ^{2} - 15 x + 22}{( x + 3 ) ( x ^{2} + 2 ) ^{2}} d x
