solvefor w,P=4(Y/(Psin(w)))

Solução

resolver para

w, P = 4 (\frac{Y}{P sin ( w )})

Solução

w = arcsin (\frac{4 Y}{P ^{2}}) + 2 πn, w = π + arcsin (- \frac{4 Y}{P ^{2}}) + 2 πn

Passos da solução

P = 4 (\frac{Y}{P sin ( w )})

Trocar lados

4 \cdot \frac{Y}{P sin ( w )} = P

Simplificar

4 \cdot \frac{Y}{P sin ( w )} : \frac{4 Y}{P sin ( w )}

4 \cdot \frac{Y}{P sin ( w )}

Multiplicar frações:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{Y \cdot 4}{P sin ( w )}

\frac{4 Y}{P sin ( w )} = P

Multiplicar ambos os lados por

sin (w)

\frac{4 Y}{P sin ( w )} = P

Multiplicar ambos os lados por

sin (w)

\frac{4 Y}{P sin ( w )} sin (w) = P sin (w)

Simplificar

\frac{4 Y}{P} = P sin (w)

\frac{4 Y}{P} = P sin (w)

Trocar lados

P sin (w) = \frac{4 Y}{P}

Dividir ambos os lados por

P; P \neq = 0

P sin (w) = \frac{4 Y}{P}

Dividir ambos os lados por

P; P \neq = 0

\frac{P sin ( w )}{P} = \frac{\frac{4 Y}{P}}{P}; P \neq = 0

Simplificar

\frac{P sin ( w )}{P} = \frac{\frac{4 Y}{P}}{P}

Simplificar

\frac{P sin ( w )}{P} : sin (w)

\frac{P sin ( w )}{P}

Eliminar o fator comum:

P

= sin (w)

Simplificar

\frac{\frac{4 Y}{P}}{P} : \frac{4 Y}{P ^{2}}

\frac{\frac{4 Y}{P}}{P}

Aplicar as propriedades das frações:

\frac{\frac{b}{c}}{a} = \frac{b}{c \cdot a}

= \frac{4 Y}{PP}

PP = P^{2}

PP

Aplicar as propriedades dos expoentes:

a^{b} \cdot a^{c} = a^{b + c}

PP = P^{1 + 1}

= P^{1 + 1}

Somar:

1 + 1 = 2

= P^{2}

= \frac{4 Y}{P ^{2}}

sin (w) = \frac{4 Y}{P ^{2}}; P \neq = 0

sin (w) = \frac{4 Y}{P ^{2}}; P \neq = 0

sin (w) = \frac{4 Y}{P ^{2}}; P \neq = 0

Aplique as propriedades trigonométricas inversas

sin (w) = \frac{4 Y}{P ^{2}}

Soluções gerais para

sin (w) = \frac{4 Y}{P ^{2}}

sin (x) = a \Rightarrow x = arcsin (a) + 2 πn, x = π + arcsin (a) + 2 πn

w = arcsin (\frac{4 Y}{P ^{2}}) + 2 πn, w = π + arcsin (- \frac{4 Y}{P ^{2}}) + 2 πn

w = arcsin (\frac{4 Y}{P ^{2}}) + 2 πn, w = π + arcsin (- \frac{4 Y}{P ^{2}}) + 2 πn
