Applica le proprietà inverse delle funzioni trigonometriche

cos (3 0^{\circ} + u) = 0.82

Soluzioni generali per

cos (3 0^{\circ} + u) = 0.82

cos (x) = a \Rightarrow x = arccos (a) + 36 0^{\circ} n, x = 36 0^{\circ} - arccos (a) + 36 0^{\circ} n

3 0^{\circ} + u = arccos (0.82) + 36 0^{\circ} n, 3 0^{\circ} + u = 36 0^{\circ} - arccos (0.82) + 36 0^{\circ} n

3 0^{\circ} + u = arccos (0.82) + 36 0^{\circ} n, 3 0^{\circ} + u = 36 0^{\circ} - arccos (0.82) + 36 0^{\circ} n

Risolvi

3 0^{\circ} + u = arccos (0.82) + 36 0^{\circ} n : u = arccos (0.82) + 36 0^{\circ} n - 3 0^{\circ}

3 0^{\circ} + u = arccos (0.82) + 36 0^{\circ} n

Spostare

3 0^{\circ}

a destra dell'equazione

3 0^{\circ} + u = arccos (0.82) + 36 0^{\circ} n

Sottrarre

3 0^{\circ}

da entrambi i lati

3 0^{\circ} + u - 3 0^{\circ} = arccos (0.82) + 36 0^{\circ} n - 3 0^{\circ}

Semplificare

u = arccos (0.82) + 36 0^{\circ} n - 3 0^{\circ}

u = arccos (0.82) + 36 0^{\circ} n - 3 0^{\circ}

Risolvi

3 0^{\circ} + u = 36 0^{\circ} - arccos (0.82) + 36 0^{\circ} n : u = 36 0^{\circ} - arccos (0.82) + 36 0^{\circ} n - 3 0^{\circ}

3 0^{\circ} + u = 36 0^{\circ} - arccos (0.82) + 36 0^{\circ} n

Spostare

3 0^{\circ}

a destra dell'equazione

3 0^{\circ} + u = 36 0^{\circ} - arccos (0.82) + 36 0^{\circ} n

Sottrarre

3 0^{\circ}

da entrambi i lati

3 0^{\circ} + u - 3 0^{\circ} = 36 0^{\circ} - arccos (0.82) + 36 0^{\circ} n - 3 0^{\circ}

Semplificare

u = 36 0^{\circ} - arccos (0.82) + 36 0^{\circ} n - 3 0^{\circ}

u = 36 0^{\circ} - arccos (0.82) + 36 0^{\circ} n - 3 0^{\circ}

u = arccos (0.82) + 36 0^{\circ} n - 3 0^{\circ}, u = 36 0^{\circ} - arccos (0.82) + 36 0^{\circ} n - 3 0^{\circ}
