Question

calcule cossec π/6+ sen π/6

Answer 1

$\large\boxed{\begin{array}{l}\sf sen\bigg(\dfrac{\pi}{6}\bigg)=\dfrac{1}{2}\\\sf cossec\bigg(\dfrac{\pi}{6}\bigg)=\dfrac{1}{sen\bigg(\dfrac{\pi}{6}\bigg)}=\dfrac{1}{\dfrac{1}{2}}=2\\\\\sf sen\bigg(\dfrac{\pi}{6}\bigg)+cossec\bigg(\dfrac{\pi}{6}\bigg)=\dfrac{1}{2}+2=\dfrac{1+4}{2}=\dfrac{5}{2}\end{array}}$
