sen 45° + sen 120°

Q: sen 45° + sen 120°

Para calcular $ \sin 45^\circ + \sin 120^\circ $: \[ \sin 45^\circ = \frac{\sqrt{2}}{2} \] \[ \sin 120^\circ = \sin (180^\circ - 60^\circ) = \sin 60^\circ = \frac{\sqrt{3}}{2} \] Portanto, \[ \sin 45^\circ + \sin 120^\circ = \frac{\sqrt{2}}{2} + \frac{\sqrt{3}}{2} = \frac{\sqrt{2} + \sqrt{3}}{2} \]

Accepted Answer

Para calcular $ \sin 45^\circ + \sin 120^\circ $:

$$
\sin 45^\circ = \frac{\sqrt{2}}{2}
$$

$$
\sin 120^\circ = \sin (180^\circ - 60^\circ) = \sin 60^\circ = \frac{\sqrt{3}}{2}
$$

Portanto,

$$
\sin 45^\circ + \sin 120^\circ = \frac{\sqrt{2}}{2} + \frac{\sqrt{3}}{2} = \frac{\sqrt{2} + \sqrt{3}}{2}
$$
