The values of sin A are as follows:-

$\leadsto\tt{sin\:{0}^{\circ}=0}$

$\leadsto\tt{sin\:{30}^{\circ}=\dfrac{1}{2}}$

$\leadsto\tt{sin\:{45}^{\circ}=\dfrac{1}{\sqrt{2}}}$

$\leadsto\tt{sin\:{60}^{\circ}=\dfrac{\sqrt{3}}{2}}$

$\leadsto\tt{sin\:{90}^{\circ}=1}$

Other values :-

• For cos A

$\leadsto\tt{cos\:{0}^{\circ}=1}$

$\leadsto\tt{cos\:{30}^{\circ}=\dfrac{\sqrt{3}}{2}}$

$\leadsto\tt{cos\:{45}^{\circ}=\dfrac{1}{\sqrt{2}}}$

$\leadsto\tt{cos\:{60}^{\circ}=\dfrac{1}{2}}$

$\leadsto\tt{cos\:{90}^{\circ}=0}$

• For tan A

$\leadsto\tt{tan\:{0}^{\circ}=0}$

$\leadsto\tt{tan\:{30}^{\circ}=\dfrac{1}{\sqrt{3}}}$

$\leadsto\tt{tan\:{45}^{\circ}=1}$

$\leadsto\tt{tan\:{60}^{\circ}=\sqrt{3}}$
