solvefor k,f=x^{2/3}+(10-x^2)^{0.5}sin(kpix)

Soluzione

risolvere per

k, f = x^{\frac{2}{3}} + (10 - x^{2})^{0.5} sin (kπ x)

Soluzione

k = \frac{arcsin ( \frac{f - x ^{\frac{2}{3}}}{( - x ^{2} + 10 ) ^{\frac{1}{2}}} )}{π x} + \frac{2 n}{x}, k = \frac{1}{x} + \frac{arcsin ( - \frac{f - x ^{\frac{2}{3}}}{( - x ^{2} + 10 ) ^{\frac{1}{2}}} )}{π x} + \frac{2 n}{x}

Fasi della soluzione

f = x^{\frac{2}{3}} + (10 - x^{2})^{0.5} sin (kπ x)

Scambia i lati

x^{\frac{2}{3}} + (10 - x^{2})^{0.5} sin (kπ x) = f

Spostare

x^{\frac{2}{3}}

a destra dell'equazione

x^{\frac{2}{3}} + (10 - x^{2})^{0.5} sin (kπ x) = f

Sottrarre

x^{\frac{2}{3}}

da entrambi i lati

x^{\frac{2}{3}} + (10 - x^{2})^{0.5} sin (kπ x) - x^{\frac{2}{3}} = f - x^{\frac{2}{3}}

Semplificare

(10 - x^{2})^{0.5} sin (kπ x) = f - x^{\frac{2}{3}}

(10 - x^{2})^{0.5} sin (kπ x) = f - x^{\frac{2}{3}}

Dividere entrambi i lati per

(10 - x^{2})^{0.5}; x \neq = 10, x \neq = - 10

(10 - x^{2})^{0.5} sin (kπ x) = f - x^{\frac{2}{3}}

Dividere entrambi i lati per

(10 - x^{2})^{0.5}; x \neq = 10, x \neq = - 10

\frac{( 10 - x ^{2} ) ^{0.5} sin ( kπ x )}{( 10 - x ^{2} ) ^{0.5}} = \frac{f}{( 10 - x ^{2} ) ^{0.5}} - \frac{x ^{\frac{2}{3}}}{( 10 - x ^{2} ) ^{0.5}}; x \neq = 10, x \neq = - 10

Semplificare

\frac{( 10 - x ^{2} ) ^{0.5} sin ( kπ x )}{( 10 - x ^{2} ) ^{0.5}} = \frac{f}{( 10 - x ^{2} ) ^{0.5}} - \frac{x ^{\frac{2}{3}}}{( 10 - x ^{2} ) ^{0.5}}
