Úprava trigonometrického výrazu
Uprav následující výraz:
\( \large \cos \left( \Large \frac{\pi}{3}\large + b \right) - \sin \left( \Large \frac{\pi}{3}\large + b \right) \)
\( \large \Large \frac{1-\sqrt {3}}{2}\large \cos b- \Large \frac{\sqrt {3}+1}{2}\large \sin b \)
\( \large \Large \frac{1+\sqrt {3}}{2}\large \cos b- \Large \frac{\sqrt {3}-1}{2}\large \sin b \)
\( \large \Large \frac{\sqrt {3}-1}{2}\large \cos b+ \Large \frac{1+\sqrt {3}}{2}\large \sin b \)
\( \large \Large \frac{\sqrt {3}+1}{2}\large \cos b+ \Large \frac{1-\sqrt {3}}{2}\large \sin b \)
