solvefor x,z=arcsin(x/(sqrt(x^2+y^2)))

Lösung

löse nach

x, z = arcsin (\frac{x}{x ^{2} + y ^{2}})

Lösung

x = \frac{y ^{2} sin ^{2} ( z )}{1 - sin ^{2} ( z )}, x = - \frac{y ^{2} sin ^{2} ( z )}{1 - sin ^{2} ( z )}

Schritte zur Lösung

z = arcsin (\frac{x}{x ^{2} + y ^{2}})

Tausche die Seiten

arcsin (\frac{x}{x ^{2} + y ^{2}}) = z

Wende die Eigenschaften der Trigonometrie an

arcsin (\frac{x}{x ^{2} + y ^{2}}) = z

arcsin (x) = a \Rightarrow x = sin (a)

\frac{x}{x ^{2} + y ^{2}} = sin (z)

\frac{x}{x ^{2} + y ^{2}} = sin (z)

Löse

\frac{x}{x ^{2} + y ^{2}} = sin (z) : x = \frac{y ^{2} sin ^{2} ( z )}{1 - sin ^{2} ( z )}, x = - \frac{y ^{2} sin ^{2} ( z )}{1 - sin ^{2} ( z )}

\frac{x}{x ^{2} + y ^{2}} = sin (z)
